CUORE Noise Reduction using Decorrelation and Filtering

The Cryogenic Underground Observatory for Rare Events (CUORE) is a ton scale experimental search for 0$\nu\beta\beta$ decay on ${}^{130}$Te. The CUORE detector consists of 988 TeO$_2$ crystals operating at $\sim$15mK. CUORE sensitivity can be enhanced by both improving the resolution and by lowering the trigger thresholds leading to better rejection of multi-coincidence background events. Both these can be achieved via noise reduction: in this talk we present a method for the removal of multi-crystal correlated noise and its performance in terms of resolution improvement.
