DESCRIPTION:Speakers: Vedran Brdar (Oklahoma State University (US))\n\nThi
 s talk is split into two parts. I will start by presenting the potential o
 f the DUNE near detector to search for new physics by focusing on axion-l
 ike particles (ALPs). In particular\, I will show how the liquid-argon de
 tector can explore currently unconstrained regions of ALP parameter space
 \, and I will also discuss how a future gaseous-argon detector or running 
 DUNE in beam-dump mode could provide an essentially background-free envir
 onment for new physics searches. The second part of the talk is focused o
 n the 220 PeV neutrino event recently reported by KM3NeT.The absence of co
 mparable events in IceCube creates a 2-3σ tension\, depending on the type
  of neutrino source. The 220 PeV neutrino detected at KM3NeT traversed ap
 proximately 150 km through rock and sea\, whereas neutrinos from the same
  location in the sky would cross only about 10 km of ice to reach IceCube
 . I will show how this difference in propagation distance helps to resolve
  this tension by considering models with light sterile neutrinos that par
 tially convert into active neutrinos.\n\nhttps://indico.global/event/17318
