Abstract
We have measured the longitudinal analyzing power Az of the pp→ppπ0 reaction at 375 MeV bombarding energy. We find that for certain angle combinations of the outgoing particles the observed Az is as large as 0.3, demonstrating that sizeable longitudinal analyzing powers in reactions with multi-particle final states are possible. This result has implications for pp parity violation experiments above the pion threshold. The observed Az is dominated by the interference between s and p wave pions in conjunction with nucleon-nucleon P waves in the final state.
