VIRTUAL INPA SEMINAR | Erin Hansen (UC Berkeley)
April 23, 2021 @ 12:00 pm - 1:00 pm
Speaker: Erin Hansen (UC Berkeley)
Title: Progress on the search for 2νββ of 130-Te to excited states of 130-Xe with CUORE
Abstract:
The CUORE experiment is a ton-scale bolometric array searching for the lepton number violating neutrinoless double-beta decay (0νββ) in the isotope 130-Te. While a discovery of 0νββ would herald new physics, the Standard Model process of two-neutrino double-beta decay (2νββ) in 130-Te has been measured in CUORE. In such cases where the isotope decays to an excited state of the daughter, 130-Xe, gammas are emitted leading to events whose energy is spread across multiple crystals. CUORE is currently searching for this decay mode, as understanding the branching ratio and spectral shape for such 2νββ decays to excited states can improve nuclear modelling and help constrain the matrix elements involved in searches for 0νββ. This talk will describe the status of and progress towards an improved search for 2νββ decays to excited states with an increased exposure of CUORE as well as additional analysis features. By exploiting the segmented nature of the CUORE detector, the scope of event signatures considered in the search is expanded and further accompanied by an improved efficiency of signal containment.
