Parity Violation in Proton-Proton Scattering at 221 MeV
Abstract
TRIUMF experiment 497 has measured the parity violating longitudinal analyzing power, Az, in pp elastic scattering at 221.3 MeV incident proton energy. This paper includes details of the corrections, some of magnitude comparable to Az itself, required to arrive at the final result. The largest correction was for the effects of first moments of transverse polarization. The addition of the result, Az=(0.84 0.29 (stat.) 0.17 (syst.)) × 10-7, to the pp parity violation experimental data base greatly improves the experimental constraints on the weak meson-nucleon coupling constants hpp and hppω, and has implications for the interpretation of electron parity violation experiments.
