SUMMARY:Observation of Excess Electronic Recoil Events in XENON1T
DESCRIPTION:We report results from searches for new physics with low-energy electronic recoil data recorded with the XENON1T detector. With an exposure of 0.65 tonne-years and an unprecedentedly low background rate of 76 ± 2 events/(tonne x year x keV) between 1-30 keV\, the data enables competitive searches for solar axions\, an enhanced neutrino magnetic moment using solar neutrinos\, and bosonic dark matter. An excess over known backgrounds is observed below 7 keV\, rising towards lower energies and prominent between 2–3 keV. The excess is interpreted as due to the physics channels mentioned above\, as well as due to a new source of background previously not considered\, as the beta decay of tritium. \n\n\n\nIstruzioni per partecipare: \nLa connessione ai seminari online dovrà essere effettuata tramite Vibe. \nPer partecipare è possibile scegliere tra due modalità: \n·collegarsi tramite il client di Vibe ( *download)\, inserendo semplicemente il proprio nome e il Meeting ID: 4856329430 (opzione consigliata) \n  \nLink: \n\n\n\n\n\n\n\n\n\n\n\n\n\nhttps://vibe.ezuce.com/launcher/?meetingID=4856329430 \nOr by using WebRTC in Chrome or Firefox :\nhttps://vibe.ezuce.com/webrtc/?meetingID=4856329430\n\n\n\n\n\n\n\n\n\n\n\n\n\n(*) Versioni richieste: \n  \n\nWindows 7 or newer\n\n\nMac OS 10.8.5 or higher\n\n\nLinux 3-4 years old\, version 7 or higher
