Description

The longitudinal analyzing power, Az, has been measured in p and ar;p elastic scattering at an incident proton energy of 221 MeV. The result obtained is Az = (0.84 ± 0.29(stat.) ± 0.17(syst.)) x 10-7. This experiment is unique in that it selects a single parity-violating transition amplitude (3P2-1D2) and consequently constrains the weak meson-nucleon coupling constant hppr. The experimental value of hppr is (-25 ± 10) x 10-7 and is found to be consistent with theoretical predictions, both in sign and magnitude. The experimental result, based on three major data runs, marks the first independent measurement of the hppr coupling constant. (author)
