Title:  RELICS: A liquid xenon time projection chamber for CEvNS detection

Speaker:  高飛（清華大學物理系）

Abstract:

Neutrino-nucleus coherent scattering, also known as CEvNS, is a highly promising method for monitoring nuclear reactors from a distance thanks to its large cross-section. A precise determination of the CEvNS cross-section significantly impacts understanding the properties of neutrinos and constraining new physics beyond the standard model. However, the biggest challenge faced by CEvNS detectors is lowering the energy threshold to keV and sub-keV while mitigating the cosmogenic background at sea level. One of the most promising technologies for CEvNS search is the liquid xenon time projection chamber (LXeTPC), which boasts a well-established low background and energy threshold. The RELICS (REactor neutrino LIquid xenon Coherent Scattering experiment) experiment aims to detect reactor CEvNS using an LXeTPC. In this presentation, I will introduce the RELICS experiment, focusing on its status and discovery potential for CEvNS signals from reactor neutrinos.
