Waveform Simulation for Pulse Shape Analysis Validation

Background reduction techniques are critical for successful detection of rare events. To facilitate its search for neutrinoless double beta ($0\nu\beta\beta$) decay, the \textsc{Majorana Demonstrator} aims to achieve a background goal of $<3$ counts/tonne-year in the $4$-keV-wide region of interest. The p-type point contact germanium detectors used in the \textsc{Demonstrator} are sensitive to the distribution of interaction sites in the crystal bulk. The signal generated by single-site events, such as the {$0\nu\beta\beta$} decay signal, can be distinguished from multi-site background events using a pulse shape analysis (PSA) algorithm. The details of a simulation-based framework to validate PSA techniques are presented here.
