Description

To reconstruct the energy and time of events in the liquid scintillator detector, in a neutrino or dark matter experiment, we need to analyze the waveforms from photomultiplier tubes (PMTs). Fast Stochastic Matching Pursuit (FSMP) samples the posterior of PE time sequence for each waveform. It gains acceleration on GPU, and improves the energy and time resolution of LS detectors. The energy resolution is improved by decreasing $12\%$ of relative resolution.
