Beschreibungen/Notizen

• We have measured the longitudinal analyzing power A z of the pp→pp π 0 reaction at 375 MeV bombarding energy. We find that for certain angle combinations of the outgoing particles the observed A z 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 A z is dominated by the interference between s and p wave pions in conjunction with nucleon-nucleon P waves in the final state.
