SUMMARY:Speaker: Antoine Armatol-Title:Investigation of the Majorana nature of neutrinos at a few meV level of the neutrino mass scale: from CUPID to BINGO
DESCRIPTION:This is an In-Person [HYBRID] Event \nLOCATION: Sessler Conference Room – 50A – 5132 \nDATE: May 5\, 2023 \nTIME: 12:00- 1:00 PM \nTITLE: Investigation of the Majorana nature of neutrinos at a few meV level of the neutrino mass scale: from CUPID to BINGO \nABSTRACT: The search for neutrinoless double beta decay (0ν2β) is one of the biggest experimental challenges of contemporary physics. Its discovery would be ground- breaking since it would prove the Majorana nature of neutrinos\, give an insight into neutrino mass scale\, and provide clues to explain the matter/antimatter asymmetry of our Universe. Cryogenic calorimeters are promising devices for this purpose as CUORE\, the ton-scale experiment constructed with such detectors\, is demonstrating by setting the most stringent limit on Te-130 0ν2β half-life and being one of the most sensitive current generation experiments. However\, its sensitivity is limited by the background. Its successor\, the next-generation experiment CUPID\, will reach a higher sensitivity by reducing the number of expected background events in the region of interest. It will study as the candidate isotope Mo-100 embedded inside Li2MoO4 scintillating crystals\, which allows mitigating the Ɣ background naturally while also introducing a dual heat/light readout using an auxiliary Ge bolometer to get rid of the α background. Thanks to that\, CUPID will improve the CUORE sensitivity by two orders of magnitude. At that point\, if 0ν2β still eludes us\, the background reduction must be pushed even further. BINGO is a project aiming to prepare the next-next generation of bolometric experiments by proposing innovations and methods for that purpose. For example\, it will reduce the remaining Ɣ and β background contributions thanks to respectively a cryogenic active veto and a revolutionary detector assembly. BINGO will demonstrate that\, once implemented in a ton-scale isotope experiment\, its improvements will allow the latter to reach a sensitivity to neutrino mass scale below 10 meV. In that talk\, the current status of the CUPID experiment will be discussed and the R&D work done in the framework of the BINGO project will be presented. \nJoin Zoom  \nhttps://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011\nPasscode: 247722

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
