Poster Neutrinoless double beta decay Poster


The CUORE Upgrade with Particle Identification (CUPID) experiment will be the successor of the CUORE experiment, a ton-scale detector currently looking for neutrinoless double beta ($0\nu\beta\beta$) decay at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy. CUPID will cover the full neutrino mass regime in the Inverted Ordering (IO) scenario, as well as the portion of the Normal Ordering (NO) regime with $m_{lightest}>10$ meV. In order to meet CUPID’s background index (B.I.) goal, backgrounds will need to be reduced by a factor of 100 compared to CUORE’s current B.I . One of these backgrounds are produced by cosmogenic muons, either by directly depositing energy in our detector or from secondaries arising from muon-induced spallation. On this poster, I will present the initial design of an active muon-tagger which will reduce the muon-induced background by multiple orders of magnitude by achieving a rejection efficiency > 99%, thus allowing CUPID to meet its target background budget.
