Abstract

We present two novelties in our analysis of fully dynamical QCD+QED ensembles with C* boundary conditions. The first one is the explicit computation of the sign of the Pfaffian. We present an algorithm that provides a significant speedup compared to traditional methods. The second one is a reweighting of the mass in the context of the RHMC. We have tested the techniques on both pure QCD and QCD+QED ensembles with pions at mπ± ≈ 400 MeV, a lattice spacing of a ≈ 0.05 fm, a fine-structure constant of αR = 0 and 0.04.
