SUMMARY:INPA Seminar Speaker: Shenyang Shi (Columbia University)- Title: Search for dark matter and solar neutrinos with XENONnT
DESCRIPTION:Date: March 13\, 2026 \nTime: 12:00 pm – 1:00 pm \nLocation: Sessler Conference Room – 50A-5132 [Hybrid and In-Person] \nSpeaker:  Shenyang Shi (Columbia University) \nTitle: Search for dark matter and solar neutrinos with XENONnT  \nAbstract: The primary goal of the XENONnT experiment is the direct detection of Weakly Interacting Massive Particles (WIMPs)\, with a projected sensitivity improvement of an order of magnitude over XENON1T. In this talk\, I will present recent results from searches for light dark matter and solar neutrinos using the scintillation-ionization channel and the ionization-only channel with a lowered detection threshold in ~7 tonne*years of exposure. Together\, these complementary analyses set world-leading constraints on dark matter–nucleon and dark matter–electron scattering cross sections. In the relevant mass range\, the sensitivity approaches the so-called neutrino fog\, where coherent neutrino scattering constitutes an irreducible background that can mimic light dark matter interactions. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011 \nPasscode: 247722
