Optical Simulations for the Muon Veto System for 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 (0νββ). CUPID aims to decrease their experimental backgrounds by a factor of a 100 compared to CUORE which will result in a 10 times improvement in the half-life sensitivity. In order to reduce the cosmogenic backgrounds CUPID will implement a muon veto system consisting of scintillator panels and read out with SiPMs. A high light collection is important in order to distinguish muons from other backgrounds. This talk will focus on the simulations being developed to optimize the scintillating panel design to maximize the light collection for the muon veto system.
