Nucleon Decay Constants from 2+1 Flavour Domain Wall Fermions

Presenter: Paul Cooney — University of Edinburgh

Paul Cooney for the RBC and UKQCD Collaborations

The low energy constants α and β involved in nucleon decay can be calculated via a ratio of correlation functions on a lattice. We present results for these nucleon decay constants on 2+1 flavour domain wall fermion lattices of spatial volume (2 fm)3 and (3 fm)3 with lattice spacing a−1=1.62(4).
