SUMMARY:INPA SEMINAR SPEAKER: Dacheng Xu(Columbia University)- Title: Measurement of the Solar Boron-8 Neutrino Fog with XENONnT
DESCRIPTION:Date: August 7\, 2026 \nTime: 12:00 pm – 1:00 pm \nLocation: Sessler Conference Room – 50A-5132 [Hybrid and In-Person] \nSpeaker: Dacheng Xu (Columbia University)  \nTitle: Measurement of the Solar Boron-8 Neutrino Fog with XENONnT \nAbstract: Coherent elastic neutrino–nucleus scattering (CEvNS) of solar neutrinos is a fundamental Standard Model process and an irreducible background for next-generation dark matter searches\, often referred to as the “neutrino fog.” With its large exposure and ultra-low background\, XENONnT has reached the sensitivity required to observe this interaction. Using data from the first three science runs\, we have searched for Boron-8 solar neutrino CEvNS and rejected the background-only hypothesis at 3.3 sigma. In this talk\, I will present a detailed view of the search for solar Boron-8 CEvNS using the full analyzed dataset and discuss its implications for beyond-Standard-Model neutrino physics and light dark matter in neutrino fog. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011 \nPasscode: 247722
