Description
The rare hyperon decay $\Sigma \to p \ell^+ \ell^-$ is a flavour changing neutral current process that is sensitive to new physics beyond the Standard Model. However, its theoretical prediction is currently limited by poorly constrained hadronic form factors. In this talk we present the theoretical framework for calculating this process on the lattice, as well as the current status of an exploratory calculation at heavy pion mass with domain wall fermions.
