TL;DR

This paper investigates hadronic parity violation in nucleon-nucleon interactions using pionless effective field theory, focusing on observables like scattering asymmetries and polarization effects.

Contribution

It applies pionless effective field theory to compute parity-violating observables in two-nucleon systems, providing a theoretical framework for these measurements.

Findings

Calculated cross-section asymmetries in nucleon-nucleon scattering.

Predicted asymmetries and polarizations in np → dγ process.

Established effective field theory approach for hadronic parity violation.

Abstract

We present results for two-body observables that are sensitive to the parity-violating component of nucleon-nucleon interactions. These interactions are studied using an effective field theory in which the only dynamic degrees of freedom are nucleon fields. The observables we study are cross-section asymmetries in nucleon-nucleon scattering and asymmetries and induced polarizations in the process np \to d\gamma.
