"Status and Analysis of the NPDGamma Experiment"
 Slideshow (PDF)

The NPDGamma Experiment measured the parity violating gamma asymmetry from polarized neutrons captured on protons at the Spallation Neutron Source at ORNL. This parity violating asymmetry is proportional to the isovector contribution of the hadronic weak interaction (HWI) and has been measured to a precision of 13ppb which can help resolve the unconstrained coupling space of the HWI. As one of the parallel analyses of NPDGamma, we present a statistically optimal algorithm using a least squares fit to the 60Hz neutron pulses in order to filter, and make high level cuts on, production data.
