Nucleon-nucleon charge symmetry breaking and the dd -> alpha pi0 reaction

TL;DR

This paper investigates how charge symmetry violation in nucleon interactions constrains the amplitude of the dd -> alpha pi0 reaction, providing insights into fundamental symmetry breaking in nuclear physics.

Contribution

It introduces constraints on the dd -> alpha pi0 reaction amplitude based on charge symmetry violating differences in nucleon scattering lengths.

Findings

Abstract

We show that using parameters consistent with the charge symmetry violating difference between the strong nn and pp scattering lengths provides significant constraints on the amplitude for the dd -> alpha pi0 reaction.
