S@INT Seminar: "CUPID, CUPID-1T, and the future of neutrinoless double beta decay"

Erin Hansen - University of California, Berkeley
Thursday, December 1, 2022 - 10:30am
PAT C-421 (participants are welcome to join via Zoom as well)

Despite years of intense focus, there is much still to learn about neutrinos; for example, the absolute neutrino mass scale and potential Majorana masses are still unknown, requiring exploration of physics beyond the Standard Model. Searches for neutrinoless double beta decay have moved to the ton-scale, spanning the isotopes available to undergo this rare process and providing information about Majorana masses of neutrinos. This talk will highlight a selection of current and future efforts toward discovery of neutrinoless double beta decay, including recent results from CUORE --- a search for 0νββ in 130Te using a bolometric array of TeO2 crystals and is currently taking data at Gran Sasso National Laboratory (LNGS). I will also discuss hardware and software advances toward CUPID, the successor to CUORE, which will search for 0νββ in 100Mo with additional sensitivity from scintillation signals in Li2MoO4. Finally, we will look ahead toward the future of 0νββ, as next-to-next generation detectors like CUPID-1T begin R&D --- I will focus specifically on readout improvements and background reduction techniques which are the target of the DEMETER demonstrator experiment at UC Berkeley.

The speaker for this event will lead the meeting remotely. All interested graduate students and faculty are invited to attend by convening in the INT Seminar Room (C-421).

Participants are also welcome to join via Zoom. Zoom link will be available via announcement email, or by contacting: gsj6[at] or prau[at]
