Parity violation in neutron capture on the proton: determining the weak pion-nucleon coupling (1501.01832v2)
Published 8 Jan 2015 in nucl-th, hep-ph, and nucl-ex
Abstract: We investigate the parity-violating analyzing power in neutron capture on the proton at thermal energies in the framework of chiral effective field theory. By combining this analysis with a previous analysis of parity violation in proton-proton scattering, we are able to extract the size of the weak pion-nucleon coupling constant. The uncertainty is significant and dominated by the experimental error which is expected to be reduced soon.
