Particle Physics Seminar

"Study of the detection of supernova neutrinos"

Presented by Hanyu Wei, Tsinghua University

Friday, August 5, 2016, 10:00 am — Small Seminar Room, Bldg. 510

A core-collapse supernova explosion would release an enormous amount of neutrinos, the detection of which could yield answers to many questions of supernova dynamics and neutrino physics. The collective neutrinos from all the past supernovae all over the universe (supernova relic neutrinos) are also observable, and their detection would provide us an insight of the stellar evolution and cosmology. In this talk, I will first introduce the supernova burst neutrinos as well as supernova relic neutrinos. Then, i will present the design, characteristics, and sensitivity of an online trigger system of supernova burst neutrinos at Daya Bay. I will also present a search for supernova burst neutrinos at Daya Bay using about 600 days of data. At last, a sensitivity study of the discovery potential for supernova relic neutrinos with a slow liquid scintillator will be presented, which is highly recommended to kilo-ton-scale detectors.
