Charged-Current Interactions in LXe TPCs
Recent observations of low-lying isomeric states in the nuclear strucutre of (^{136})Cs indiciate that charged-current interacitons on (^{136}) (136Xe-CC) will create time-delayed coincident signals in LXe TPCs such as nEXO. These unique signals can be leveraged for remarkable abckground rejeciton on the order of (10^{-9}), enabling backgorund free studies in LXe TPCs. In particular, I study how these unique signals can allow nEXO to serve as a background free solar neutrino and dark matter detector, in addition to its primary role as a neutrinoless double beta decay detector.
