Neutrino echoes as a probe of neutrino secret interactions
Mr. José A. Carpio (Penn State University)
Abstract: As astrophysical neutrinos propagate from the source to the observer, they may interact with the surrounding dark matter or the cosmic neutrino background through Beyond Standard Model interactions. Upon scattering, the trajectory length increases and will cause some neutrinos to be delayed. In this talk, I will discuss the properties of this delayed signal and how next-generation neutrino detectors can probe neutrino-neutrino interactions with a light scalar mediator and neutrino-dark matter coupling to a vector mediator.
