  1. 155. Contributed Talk: Probing Heavy Axions in Astrophysical Objects
    Takuya Okawa (Washington University in St. Louis)
    6/27/25, 3:15 PM

    Author and Presenter: Takuya Okawa
    Abstract: Hot plasma in astrophysical objects provides an ideal place for the production of heavy axion-like particles (ALPs). We show that a fraction of these ALPs could stream out of the photosphere and subsequently decay into two photons that can be potentially detected on or near the Earth. In particular, we estimate the photon flux originating from the...

  3. 55. Plenary Talk: The Secret Life of WIMP and FIMP dark-matter- Beyond Visible Dimensions
    Dipan Sengupta (University of New South Wales)
    6/27/25, 4:15 PM

    Author and Presenter: Dipan Sengupta
    Abstracts: Extra-dimensional models where Kaluza-Klein particles mediate interactions of a dark sector with the Standard Model particles have recently found a renewed interest. This talk will explore some deeper theoretical and phenomenological issues within these set-ups, both in the context of WIMP and FIMP dark matter models. I will demonstrate that...

  4. 52. Parallel Talk: Discovering Axion-like Particles (ALPs) Using CMB as a Backlight
    Harsh Mehta
    6/27/25, 4:45 PM

    Author: Harsh Mehta
    Co-author: Suvodip Mukherjee
    Presenter: Harsh Mehta
    Abstract: Axions or axion-like particles (ALPs) are hypothetical particles predicted by various BSM theories, which also make one of the dark matter candidates. If ALPs exist in nature, the CMB photons as they pass through galaxy clusters will convert to ALPs (of mass range 10−14 to 10−11 eV), resulting in a polarized...
