The Higgs potential is vital to understand the electroweak symmetry breaking mechanism, and probing the Higgs self-interaction is arguably one of the most important physics targets at current and upcoming collider experiments. In particular, the triple Higgs coupling may be accessible at the HL-LHC by combining results in multiple channels, which motivates to study all possible decay modes for...

A thallium doped sodium iodide (NaI(Tl)) crystal is a conventional detector with a very long history and is still widely used for a particle detector. In particular, since the DAMA/LIBRA experiment claimed an observation of dark matter with the NaI(Tl) detector, low background and high light yield detectors have been developed. In Korea, the COSINE-100 experiment to verify the DAMA/LIBRA...

Finding neutrinoless double beta decays would establish the Majorana nature of neutrinos. The AMoRE experiment aims at searching for neutrinoless double beta decay of 100Mo using a simultaneous heat and scintillation detection technique with crystals operating at mK temperatures. We planned the AMoRE experiment in a three-stage program, AMoRE-pilot, AMoRE-I, and AMoRE-II. Currently, the...

We revisit the role of a sub-component dark matter in well motivated multi-component dark matter scenarios beyond WIMP. When the sub-component is a messenger between the dark sector and the SM sector, especially in boosted dark matter scenarios, it can provide distinctive signatures in various dark matter and neutrino experiments. In addition, we show the dynamics of a sub-component dark...

The axion is a hypothetical particle arising from the Peccei-Quinn mechanism which was proposed to solve the strong CP problem. It is also one of the most popular candidates for dark matter since it barely interacts with ordinary matter and is thought abundant in the universe. Therefore, the discovery of the axion can be referred to as a hunt for two birds (the strong CP and dark matter...

Non-standard neutrino interactions with a massive boson can produce the bosons in the core of core-collapse supernovae (SNe). After the emission of the bosons from the SN core, their subsequent decays into neutrinos can modify the SN neutrino flux. We show future observations of neutrinos from a next galactic SN in Super-Kamiokande (SK) and Hyper-Kamiokande (HK) can probe flavor-universal...

The 80% of the matter in the Universe is in the form of dark matter that comprises the skeleton of the large-scale structure called the Cosmic Web. As the Cosmic Web dictates the motion of all matter in galaxies and inter-galactic media through gravity, knowing the distribution of dark matter is essential for studying the large-scale structure. However, the Cosmic Web's detailed structure is...

General Relativity predicts that photons emitted from distant sources can be deflected by intervening gravitational potential between the sources and us. This effect is known as gravitational lensing effect, causing a coherent distortion in the shapes of observed galaxies with a large separation. The lensing effects also provide a powerful means of mapping cosmic mass density distributions and...

In this talk, we use machine learning to analyze 21cm intensity map images of the universe after reionization to explore the dark matter mass. Since dark matter mass affects the matter distribution in the universe at small scale, we can obtain information on dark matter mass by analyzing the distribution of neutral hydrogen in the 21cm intensity map.
In this study, we use hydrodynamic...

If Dark Matter (DM) has a sizable scattering cross section with nucleons, it can efficiently be captured by a neutron star. Its energy is then transferred to the neutron star as heat through the scattering and annihilation inside the star. This heating effect may be detectable via dedicated temperature observations of nearby old pulsars, providing an alternative method for DM searches. We show...

The persistent discrepancies between observationally-inferred structures and the predictions of collisionless CDM-only simulations at small scales continue to challenge our understanding of galaxy formation. In the past twenty years, new observations and simulation studies have been suggesting that the small-scale issues may be ameliorated by taking into account the physical effects of the new...

We study the impact of sphaleron-induced thermal friction on the axion dark-matter abundance due to the interaction of an axion-like particle (ALP) with a dark non-abelian gauge sector in a secluded thermal bath. Thermal friction can either enhance the axion relic density by delaying the onset of oscillations or suppress it by damping them. We derive an analytical formula for the frictional...
