Improving CUORE Energy Reconstruction Using Principal Component Analysis (PCA)

CUORE (Cryogenic Underground Observatory for Rare Events), located in the Laboratori Nazionali del Gran Sasso in Italy, is an experiment designed to search for neutrinoless double beta decay (0νββ) in 130Te. Neutrinoless double beta decay is a theoretically predicted radioactive decay process that, if observed, would determine the Majorana nature of the neutrino and indicate that lepton number is not a conserved quantity. Currently, CUORE uses a software trigger algorithm called an Optimum Filter (OF) trigger for energy reconstruction. However, OF assumes that signal shape is independent of energy, which isn't true in CUORE. A PCA-aided reconstruction could mitigate the energy dependence of pulse shapes and improve the overall energy resolution of the CUORE detector. This talk will discuss the current results of the analysis.
