    Boris Ivanov (IBS DMAG)
    25/04/2026, 11:25

    Axion haloscopes are among the most promising approaches for detecting dark matter, requiring coverage over a broad frequency range from hundreds of MHz to hundreds of GHz. The detection principle proposed by Sikivie employs high-quality microwave resonators immersed in a strong magnetic field, with sensitivity significantly enhanced by cryogenic low-noise amplification.

  7. 28. Constraints on Generalized Neutrino Interactions in the keV Region of the Tritium β-Decay Spectrum
    Jeong Yeol Yang (IBS CUP)
    25/04/2026, 11:50

    The effective Lagrangian for tritium β decay in the Standard Model can be extended by introducing additional Lorentz-invariant coupling terms analogous to those of the electroweak interaction. This framework, known as Generalized Neutrino Interactions (GNIs), incorporates interactions involving light and heavy neutrinos as well as right- and left-handed neutrino currents coupled to quarks and...

    Jaeok Yi (KAIST)
    25/04/2026, 16:20

    In this talk, we approach deep neural networks from the perspective of physics, introducing the bulk–boundary decomposition as a novel framework for analyzing their training dynamics. By treating the learning process as a physical system, we demonstrate that the stochastic gradient descent formulation yields a Lagrangian that can be cleanly separated into a data-independent bulk action and a...

    Wonkyung Kim (IBS CUP / UST)
    25/04/2026, 17:20

    We report new constraints on the spin-dependent (SD) WIMP-proton cross section using the COSINE-100 experiment at the Yangyang Underground Laboratory. This analysis achieves a pioneering detection threshold of 3 and 4 pulse clusters corresponding to the measured photoelectrons. This allows us to access the unstudied few-photoelectron regime, significantly below the previous 8-photoelectron...

  17. 18. Probing Neutrinoless Double Electron Capture in Calcium-40 with AMoRE
    Bijaya Sharma (IBS CUP)
    25/04/2026, 17:35

    The search for neutrinoless double electron capture (0ν2EC) is a powerful probe for lepton-number violation and the Majorana nature of neutrinos. We report on a search for the 0ν2EC decay of 40Ca using the AMoRE-I cryogenic detector array, which utilizes metallic magnetic calorimeters (MMCs) and 48depl.Ca100MoO4 crystals. Analyzing a total...

  18. 19. Galactic Center Excess from the 17.5 Years of Fermi-LAT Data

  19. 20. Photon Axion Enhancement around PBH
    Junghoon Joh (Sungkyunkwan University)
    25/04/2026, 18:05

    Dark matter (DM) can be gravitationally captured around a massive compact object, forming a dense halo. If primordial black holes (PBHs) exist, surrounding dark matter particles can be accreted through gravitational attraction, leading to the formation of a DM halo with a steep spike profile near the PBH.

    If the dark matter consists of axions or axion-like particles (ALPs), the high number...

  21. 22. Constraining Dark Matter with Early-Universe 21-cm Signals
    Hyunbae Park (IBS CTPU-CGA)
    26/04/2026, 09:25

    The 21-cm line of hydrogen is emerging as a promising probe of the first 0.1 billion years of cosmic history. We conduct a suite of hydrodynamical simulations to precisely model the impact of sub-Mpc structure formation on 21-cm emission during these early epochs. We find that this small-scale matter clumping turns highly nonlinear at z≲30, leading to ~10% changes in the sky-averaged 21-cm...

    Jongkuk Kim (Kangwon National University)
    26/04/2026, 11:50

    In 2023, Belle II collaboration announced the observarion of the B→K+νν decay channel for the first time. This decay channel provides a clean signal with high precision in theoretical calculation. However, we encounter 2.8σ deviation from the Standard Model prediction. To resolve this excess, we study scalar dark matter model with local discrete Z 3 Z 3 ​ symmetry. Considering dark Higgs mass...
