Reducing Cosmogenic Backgrounds in CUPID

CUPID, the CUORE Upgrade with Particle IDentification, is a proposed upgrade to CUORE,  a ton-scale bolometric experiment in search of neutrinoless double-beta decay (0??????). CUPID will be located at Gran Sasso National Laboratory (LNGS) in Italy and will search for 0?????? decay with a projected sensitivity corresponding to the full neutrino mass regime in the Inverted Ordering (IO) scenario; this correlates to a ¹⁰⁰Mo 0?????? half-life greater than T_1/2^0?? > 10²⁷ yr. To achieve the expected sensitivity, CUPID will implement several techniques to further mitigate backgrounds including scintillating bolometers for particle identification.  Additionally, CUPID will have an active muon veto system to reduce the background from muons in the region of interest. The muon veto system will have a modular design placed around and below the external shielding to tag cosmic muons and correlate them with bolometer data.  This presentation will discuss the cosmogenic background in CUPID and the use of the muon tagger for the reduction of cosmogenic backgrounds in CUPID.
