Hadronic weak interaction in the two-nucleon system with effective field theories

TL;DR

This paper reviews recent effective field theory calculations of weak interactions in two-nucleon systems, focusing on parity-violating observables in low-energy radiative neutron capture.

Contribution

It compares pionful and pionless effective field theories in calculating parity-violating effects in neutron-proton interactions.

Findings

Parity-violating observables calculated with both theories

Insights into weak interaction mechanisms at low energies

Comparison of theoretical predictions with experimental data

Abstract

Weak interactions in two-nucleon system at low energies are explored in the framework of effective field theory. We review our recent calculations of parity-violating observables in radiative neutron capture on a proton at threshold where both pionful and pionless theories are employed.
