Status of The NPDGamma Analysis

The NPDGamma Experiment was performed to measure the parity violating gamma asymmetry from polarized neutrons captured on protons at the Spallation Neutron Source at ORNL. The parity-violating (PV) neutron spin asymmetry $A_{\gamma}$ of gammas from neutron capture on protons is proportional to the $\Delta I = 1$ long range weak meson coupling $h_{\pi}^1$ between nucleons in the hadronic weak interaction (HWI). Liquid para-hydrogen production data finished in April 2014 and the preliminary result for the PV asymmetry $A_{\gamma}$ is that it is small with a statistical error of about 13 ppb, which can help constrain the HWI coupling space. Various aspects of the analysis will be discussed and $h_{\pi}^1$ will be compared to previous results.
