11:00 → 12:00 Presentation: Super-Kamiokande and the Diffuse Supernova Neutrino Background: Andrew Santos

Core-collapse supernovae are violent explosions at the end of massive stars’ lives. To understand these phenomena is to better understand the evolution of the universe, and neutrinos can serve as a complementary probe to electromagnetic radiation. In this seminar, we will introduce the physics behind neutrinos, supernovae, the Diffuse Supernova Neutrino Background (DSNB), and the Super-Kamiokande water Cherenkov experiment. After, we will focus specifically on the current best event selection to distinguish between neutrinos from the DSNB and a dominant background for this analysis, atmospheric neutrinos. This includes a new cut that has recently been incorporated into the Super-K DSNB analysis. Its validation and performance will be shown along with its consequences for increased sensitivity to detecting the DSNB at Super-K.
