The diffuse supernova neutrino background, a new window to the Universe

Dr. Yuber-Perez Gonzales
Postdoctoral Fellow
Fermi National Accelerator Laboratory

Since the first generation of stars, core-collapse supernovae have produced a steady flux of neutrinos, which could be detectable in the next-generation of experiments. Measuring such a continuous flux, known as the diffuse supernova neutrino background (DSNB), could put novel bounds on possible beyond-the-Standard Model scenarios, such as neutrino lifetimes and oscillations expected if neutrinos are pseudo-Dirac particles. Moreover, the DNSB could teach us about cosmology and astrophysics since these neutrinos have been propagating in an expanding Universe. We will explore these possibilities in this talk.
