DESCRIPTION:Observations of very-high-energy gamma-rays above 10 TeV provi
 de a new indirect probe of the extragalactic background light (EBL). In th
 is talk\, we explore the implications of observed TeV gamma-rays\, includi
 ng LHAASO data\, for Beyond-the-Standard-Model (BSM) scenarios such as dec
 ays of neutrinos\, axions\, and sterile neutrinos. By confronting these ne
 w physics scenarios with TeV gamma-ray observations\, we derive constraint
 s on the electromagnetic dipole moment couplings of the cosmic neutrino ba
 ckground\, the axion-photon coupling of axion dark matter\, and the steril
 e neutrino decay rate.\n\nhttps://indico.ibs.re.kr/event/1437/
