Lattice Calculation of Short-Range Contributions to Neutrinoless Double-Beta Decay at Physical Pion Mass
Peter Boyle, Felix Erben, Xu Feng +7
Neutrinoless double-beta () decays provide an excellent probe for determining whether neutrinos are Dirac or Majorana fermions. The short-range matrix elements associated wit…

Absorbing discretisation effects with a massive renormalization scheme: the charm-quark mass
Luigi Del Debbio, Felix Erben, Jonathan M. Flynn +2
We present the first numerical implementation of the massive SMOM (mSMOM) renormalization scheme and use it to calculate the charm quark mass. Based on ensembles with three flavour…

Charm quark mass using a massive nonperturbative renormalisation scheme
Luigi Del Debbio, Felix Erben, Jonathan Flynn +2
We present a first numerical implementation of a massive nonperturbative renormalisation scheme, RI/mSMOM, in the study of heavy quarks using the domain-wall fermion action. In par…
