Precision Measurement of Parity Violation in Polarized Cold Neutron Capture on the Proton: the NPDγ Experiment

2006

The NPDγ experiment at the Los Alamos Neutron Science Center (LANSCE) is dedicated to measure with high precision the parity violating asymmetry in the γ emission after capture of spin polarized cold neutrons in para‐hydrogen. The measurement will determine unambiguously the weak pion‐nucleon‐nucleon (πNN) coupling constant fπ1.
