“Near Detector” for Supernova Neutrino Measurements in DUNE

Dr. Yun-Tse Tsai

Detection of supernova neutrinos is one of the primary physics goals of the Deep Underground Neutrino Experiment (DUNE). However, highly significant systematic uncertainty and bias in the DUNE supernova neutrino measurements come from the discrepancies among theoretical calculations on the nu-Ar interaction cross sections with the neutrino energy in O(10 MeV), which have never been measured. In this talk, I will discuss the idea of “near detector” measurements with a liquid-argon timeprojection chamber (LArTPC), improving the precision of supernova neutrino measurements in DUNE.
