Baryon masses from full QCD+QED${}_\text{C}$ simulations
Abstract
In these proceedings we present preliminary results for the masses of the proton, neutron and baryons obtained from QCD+QED lattice simulations performed with four dynamical quarks using C boundary conditions. These results are part of the ongoing effort of the RC collaboration discussed in the companion proceedings, and have been obtained on a single ensemble in which the renormalised electromagnetic coupling is , the physical volume is fm and the masses of the four dynamical quarks have been tuned at the --spin symmetric point . We demonstrate on this unphysical ensemble that baryon masses can be calculated with satisfactory precision when including QED without the need for gauge--fixing and perturbation theory. This makes us confident in the effectiveness of the strategy presented here also in the case of simulations closer to the physical point.
