Parity violation in proton-deuteron scattering

TL;DR

This paper investigates parity violation effects in relativistic proton-deuteron scattering, estimating P-odd asymmetries in various cross sections and highlighting the advantage of polarized deuterons over protons for observing these effects.

Contribution

It provides the first estimates of P-odd asymmetries in proton-deuteron scattering within Glauber's approach, emphasizing the significance of deuteron polarization.

Findings

Significant P-odd asymmetry in deuteron dissociation channel

Deuteron-proton interaction shows larger P-odd effects than proton-deuteron

Estimates suggest measurable parity violation effects in scattering cross sections

Abstract

The effects of parity violation in the interaction of relativistic polarized protons and deuterons are discussed. Within Glauber's approach, estimates are obtained for P-odd asymmetries in the total and elastic scattering cross sections, in the deuteron dissociation cross section, and in the inelastic cross section with meson production in a final state. It is shown that, from the point of view of the magnitude of the P-odd effects, the interaction of polarized deuterons with unpolarized protons has an advantage over the interaction of polarized protons with unpolarized deuterons. A significant P-odd asymmetry was found in the dissociation channel of the polarized deuteron.
