Parity violation in pppp scattering and vector-meson weak-coupling constants

preprint2005arXivOpen access

Abstract

We calculate the parity-nonconserving longitudinal asymmetry in the elastic p⃗p\vec{p} p scattering at the energies where experimental data are available. In addition to the standard one-meson exchange weak potential, the variation of the strong-coupling constants and the non-standard effects such as form factors and 2π2 π-exchange description of the ρρ-exchange potential are taken into account. With the extra effects, we investigate the compatibility of the experimental data and the presently-known range of the vector-meson weak-coupling constants.
