SUMMARY:Speaker: Raquel Castillo Fernandez (University of Texas Arlington)- Title: In the hunt for 0νββ at the NEXT experiment
DESCRIPTION:This is an In-Person [HYBRID] Event \nLOCATION: Sessler Conference Room – 50A – 5132 \nDATE: May 12\, 2023 \nTIME: 12:00- 1:00 PM \nTITLE: In the hunt for 0νββ at the NEXT experiment \nABSTRACT: In the last decades\, oscillation experiments have demonstrated that neutrinos are not massless particles\, and the lepton number is not conserved. Thus\, revealing the nature of neutrino masses is one of the major goals in particle physics\, and the observation of the neutrinoless double beta decay (0νββ) has been identified as the most practical way to establish that neutrinos are Majorana particles\, that is\, fermions equivalent to their antiparticles. However\, 0νββ\, which would violate the lepton number by two units\, has not been observed yet and the best limits to the half-life of this process exceed 10ˆ26 yr. An extraordinary effort by several experimental collaborations is ongoing to achieve this ambitious goal and to explore the possibilities to understand the underlying physics of this process\, among them\, the NEXT experiment aims at the competitive search for the 0νββ decay in 136Xe using high-pressure gas electroluminescent time projection chambers (TPCs). In this talk\, I will discuss the status of the current prototypes that are under installation\, NEXT-100 and NEXT-CRAB\, and some of the main challenges and virtues of the 0νββ search. \nJoin Zoom  \nhttps://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011\nPasscode: 247722
