        Dark Matter from Strong CP: An Alternative View 30m
        Spacetime parity provides an important alternative to the Peccei-Quinn solution of the strong CP problem. Furthermore, it provides an understanding of why the Higgs quartic coupling is so small at very high energies. Two theories with parity restoration are discussed, one with precision gauge coupling unification and another with a new dark matter candidate. I discuss signals for a component of dark matter with colored constituents and for trace amounts of fractionally charged stable particles.

        Conversion of dark radiation to photon in early universe and 21cm signal 30m
        I discuss a possibility to convert dark radiation to photon in the early universe. In particular, I show that dark radiation consisting of axion-like particles can resonantly convert into photons under the intergalactic magnetic field. Such a conversion process can effectively heat up the Rayleigh-Jeans tail of the CMB, which may explain the anomaly in the 21cm spectrum recently reported by EDGES experiment. I also discuss possibilities of the dark radiation other than axion-like particle.

        Unification and "invisible" axion 30m
        I discuss the invisible axion arising from GUTs and string compactification. It will also include our recent calculation of the current misalignment angle, which leads to about $10^{-18}\bar{\theta}_1$ where $\bar{\theta}_1$ is the initial misalignment angle at the time $m_a=3H$.

        Astrophysical and Cosmological Searches for Axions 30m
        Axions span a vast parameter space, from axion inflation at the GUT scale, to axion dark energy at the Hubble scale. In between lie the benchmark models of the QCD axion, and “fuzzy dark matter”. Remarkably, vast swathes of this parameter space can be probed. I will review a mixed bag of such constraints and searches, with a focus on cosmology. I will also briefly discuss exciting new ideas in axion direct detection.

        Title: Search for Dark Matter at 250 GeV Lepton Colliders 30m
        The search for the (thermal)dark matter is one of important goals at future lepton colliders such as ILC and CEPC. I will discuss what kind of role these lepton colliders play on this search and figure out quantitatively what kind of the dark matter can be efficiently detected there, compared to other dark matter experiments at other collider experiments (e.g. LHC), underground experiments (direct dark matter detections) and astrophysical observations (indirect dark matter detections).

        The status and prospect for neutrino physics 30m
        The study of neutrino properties, especially those pertaining to neutrino masses and mixing, is among the most rapidly developing subjects in fundamental physics. Non-zero neutrino masses are the most palpable evidence of physics beyond the standard model and there are several current and future experiments poised to make new discoveries. I will present the current status of neutrino physics, emphasizing the open phenomenological and theoretical questions.

        Dark Matter and Structure Formation in the Universe 30m
        The cosmological model dominated by dark matter and dark energy has proven to be very successful in explaining the structure formation on large scales (>~1Mpc). There are so-called `small-scale problems’ of the Lambda-CDM model, however, many of them can be solved by astrophysical effects of baryons and feedback. I will review some of these issues, and discuss the current efforts in taking the next step in galaxy formation research using cosmological hydrodynamic simulations.

        The Current Status and Prospects for Direct Dark Matter Searches 30m
        Direct detection experiments seek to detect dark matter though its scattering off nuclei in terrestrial detectors. Over the last decade direct detection dark matter experiments have made remarkable progress in searching for the constituents of the dark matter that makes up ~80% of the matter density of the Universe. Experiments using liquid noble elements are quickly approaching a regime where they will encounter an irreducible neutrino background while solid state device is pushing bounds searching for dark matter candidates of lower masses. In this talk, I will review the motivation for the direct detection of dark matter, discuss a variety of challenges faced by experimenters trying to directly detect dark matter and review recent results from leading direct detection experiments.

        Recent PandaX-II results on dark matter search and PandaX-4T upgrade status 30m
        PandaX experiment, located at China JinPing underground Laboratory (CJPL), is a 500kg scale liquid xenon dark matter direct detection experiment. With recent data, PandaX-II experiment obtained stringent upper limits on the spin-independent (SI) and spin-dependent (SD) WIMP-nucleon elastic scattering cross sections. Alternative models of dark matter are also explored using this data. Meanwhile, PandaX collaboration has launched an upgrade plan to build PandaX-4T detector with 4-ton liquid xenon in the active volume. The PandaX-4T experiment will be relocated to CJPL-II and is expected to run after 2020. Detailed simulation indicates that the sensitivity on SI WIMP-nucleon scattering cross section could reach 10^{-47} cm^2 after two-year's running.

        Axion dark matter search at IBS/CAPP 20m
        Since its prediction, the axion has been considered as the most compelling solution to the strong-CP problem and a leading candidate for cold dark matter. The Center for Axion and Precision Physics Research (CAPP) of the Institute for Basic Science (IBS) in South Korea has completed the construction of the infrastructure for axion dark matter search experiments. Multiple experiments are currently under preparation, with one in data acquisition mode, for parallel operation targeting at different mass ranges. The ultimate goal of our center is to be sensitive to the DFSZ model over a wide range of axion mass. The current approaches to achieve this goal are three folds – commissioning of high field magnets, designing high frequency cavities, and developing low noise (nearly quantum noise limited) amplifiers. We present the status of the experiments and discuss the future prospects.

        AMoRE: A neutrinoless double beta decay experiment 20m
        The AMoRE (Advanced Molybdenum based Rare process Experiment) is looking for neutrinoless double beta decay of Mo-100 in molybdate based crystal scintillators by using a cryogenic technique. The crystals equipped with MMC (Metallic Magnetic Calorimeter) phonon and photon sensors are cooled down to 10~20 mK temperatures to detect both thermal and scintillation signals produced by a particle interaction in the crystal to achieve high energy resolution and efficient particle discrimination. The AMoRE-pilot, an R&D phase, has six 48depl Ca 100 MoO 4 crystals with a total mass of ~1.9 kg in the latest configuration and is running at the 700-m-deep YangYang underground laboratory. After the completion of the AMoRE-pilot run by autumn this year, the AMoRE-I will start with ~5 kg of crystals, mostly 48depl Ca 100 MoO 4 and several R&D crystals such as Li 2 100 MoO 4 and Na 2 100 MoO 7 . The AMoRE-II with 200 kg of molybdate crystals at the new 1,000 m deep underground laboratory (Yemi Lab) to be excavated by 2020 at Handeok iron mine can improve effective Majorana neutrino mass sensitivity down to the level of inverted hierarchy of neutrino mass, 20-50 meV. We have already secured 70 kg of Mo-100 isotope out of 120 kg contracted for the AMoRE-II experiment. Results of the AMoRE-pilot and status of the AMoRE-I and AMoRE-II preparation will be presented.

        Axionic Electroweak Baryogenesis 20m
        An axion can make the electroweak phase transition strongly first-order as required for electroweak baryogenesis even if it is weakly coupled to the Higgs sector. This is essentially because the axion periodicity helps to avoid an instability of the potential regardless of the value of the axion decay constant. Furthermore, the axion can serve as a CP phase relevant to electroweak baryogenesis if one introduces an effective axion coupling to the top quark Yukawa operator. Then, for an axion decay constant between about TeV and order 10 TeV, the observed baryon asymmetry can be explained while avoiding current experimental constraints. It will be possible to probe the axion window for baryogenesis in future lepton colliders and beam-dump experiments.

        Inflation as a Particle Collider 30m
        The conventional way to study high energy particle physics is to build particle colliders. In fact, the nature has already built a “collider” running at unprecedentedly high energy (up to 10^13 GeV): During cosmic inflation, high energy particles (up to the Hubble scale of inflation) are produced and interacts with each other. The relics of the interaction are imprinted in the density fluctuations of our current universe in a unique and model-independent way. By measuring the correlations of these density fluctuations, the particle spectrum and interactions at the energy scale of inflation can be reconstructed. This is known as the cosmological collider physics. In this talk, the cosmological collider physics, and the corresponding signature for the Standard Model are reviewed. We also discuss how the expansion history of the primordial universe can be measured by the same process.

        Signatures of particle production during inflation 30m
        We will discuss several phenomenological signatures that can result from particle production during inflation, with a particular attentions to models of axion inflation. The signatures include large non-gaussianity and sourced gravitational waves at CMB scales, primordial black holes, and gravitational waves at interferometer scales.

        Non-Gaussian gravitational waves from inflation 30m
        It has been widely assumed that detection of primordial gravitational waves from inflation in, for example, B-mode polarisation of the cosmic microwave background, immediately implies discovery of the quantum nature of spacetime. While this statement is true for the vacuum solution, it does not apply if the gravitational waves originate from the matter fields. How can we distinguish between these two origins? The answer is non-Gaussinaity. We show that the gravitational waves from SU(2) gauge fields coupled to a spectator axion field during inflation are highly non-Gaussian with a characteristic shape, whereas those from the vacuum are only weakly non-Gaussian.

        Light inflaton completing Higgs inflation 30m
        We consider the extension of the Standard Model (SM) with a light inflaton where both unitarity problem in Higgs inflation and vacuum instability problem are resolved. The linear non-minimal coupling of the inflaton to gravity leads to a significant kinetic mixing between the inflaton and the graviton such that perturbative unitarity is restored up to Planck scale. We show the correlation between unitarity scale and inflationary observables in this model and discuss how the effective Higgs inflation appears.

        Pixels to physics: the promise and challenges of survey cosmology 30m
        We are entering a transformative period in observational cosmology. Surveys starting in 2019 promise to solve key problems in cosmology — but only if we develop new approaches for handling the volume and complexity of the data. Extracting robust cosmological information from these surveys is a major challenge that will require development and validation of analysis methods at each step of the chain from raw pixels to cosmology. I will comment on some of the experimental and methodological innovations that are needed to realise the promise of upcoming surveys. I will place particular emphasis on the need for accurate diagnosis of inconsistent results from different combinations of cosmological probes, to ascertain whether such “tensions" indicate the need for new physics.

        Optical Follow-up Observation of the Gravitational Wave Source, GW170817 30m
        On August 17th 2017, for the first time in the history, the gravitational wave (GW) detectors recorded signals coming from the merger of two neutron stars.  This event was named as GW170817, and more interestingly, gamma-ray emission was detected 2 seconds after the gravitational wave signal, and 11 hours later, telescopes in Chile identified that the GW signal came from the NGC 4993 galaxy at the distance of about 40 Mpc. This is again the first time that electromagnetic (EM) signals are detected for a GW source. The follow-up observations by astronomers all around the world, including our group in Korea, successfully identified the optical emission as the kilonova, the elusive optical/NIR counterpart that has been proposed to originate from a neutron star merger. Yet again, this marks the first time that a kilonova was discovered convincingly. This whole event started the new era of astronomy, so-called the "multi-messenger astronomy", where the combined information from GW and EM radiation reveals an unprecedented view of the universe. In this talk, I summarize this exciting event, and describe the efforts by Korean astronomers that have led to important discoveries about the kilonova and the host galaxy properties, and finally provide the future prospects.

        Multi-frequency GW astronomy 30m
        Discoveries of binary black holes (BBHs) and binary neutron stars via gravitational waves (GWs) opened a new window to explore the universe. So far the GW astronomy is accessible between about 25 Hz up to 2000 Hz (by LIGO and Virgo detectors on Earth). Compact objects such as neutron stars and black holes with masses around O(1) - O(100) Solar masses are main sources in this frequency range. There are international efforts for GW observations in multi- frequency bands, in particular toward lower frequencies. For example, Pulsar Timing Array aims to detect gravitational waves in nanohertz, targeting supermassive black hole binaries. The success of the LISA Pathfinder mission of ESA (European Space Agency) proved that the technology required to detect GWs around millihertz or below in space is feasible. One of the most important information we can obtain by the multi-frequency GW observation would be the formation and evolution of compact objects in binaries, in particular BBHs, over the cosmic time. The "middle-frequency" range between 0.1-10 Hz have attention recently for the prospects of discovering intermediate-mass black holes. In addition to resolved targets, cosmic GW background calls for a broad-band or multi-frequency observation. In this review talk, I will present highlights of different proposals targeting different frequency bands and their science goals. The “multi-messenger” astronomy, in coordination with particle and electromagnetic-wave observations, will be most powerful when multi-frequency GW observations will be available. I will discuss prospects of multi-frequency, multi-messenger astronomy that would be in reality in decades, focusing on black hole astronomy and cosmology.

        Gravitational-wave astrophysics 30m
        Ground-based gravitational-wave detectors have opened new avenues to explore the universe. The detections of several binary black holes have allowed, for the first time, to access these objects without needs for photons, and to directly measure their masses and spins. The spectacular join detection of gravitational waves and light from the binary neutron star system GW170817 has shown the potential of multi-messenger astrophysics and yielded an independent measurement of the Hubble constant. In this talk, I will focus on what we can expect next, as the detectors approach their design sensitivity. I will also report on the scientific potential of the next-generation of gravitational-wave detectors, which could detect all the binary black holes in the universe.

        Status and prospect of theories on the origin of matter-antimatter asymmetry in the universe 30m
        The origin of the matter antimatter asymmetry of the universe remains unexplained in the Standard Model of particle physics. The origin of the flavour structure is another major puzzle of the theory. In this talk, we report on recent work attempting to link the two themes through the appealing framework of electroweak baryogenesis. We show that Yukawa couplings of Standard Model fermions can be the source of CP-violation for electroweak baryogenesis if they vary at the same time as the Higgs is acquiring its vacuum expectation value, offering new avenues for electroweak baryogenesis. The advantage of this approach is that it circumvents the usual severe bounds from Electric Dipole moments. These ideas apply if the mechanism explaining the flavour structure of the Standard Model is connected to electroweak symmetry breaking, as motivated for instance in Composite Higgs models.

        Utilities of Gravitational Waves for Probing Dark Matter 30m
        We propose that LIGO can see the dark matter possibly in the form of a compact object of 10 solar mass or heavier. It is through the fringe signal imprinted on the gravitational wave(GW). The fringe is a frequency-dependent interference pattern induced gravitationally when the GW passes by compact dark matter. Surprisingly, LIGO is the one that can measure this most efficiently. We discuss underlying physics and prospects of the GW fringe measurement. Refs: [1712.01396], [1710.03269]
