A first look at maximally twisted mass lattice QCD calculations at the physical point

Abstract

In this contribution, a first look at simulations using maximally twisted mass Wilson fermions at the physical point is presented. A lattice action including clover and twisted mass terms is presented and the Monte Carlo histories of one run with two mass-degenerate flavours at a single lattice spacing are shown. Measurements from the light and heavy-light pseudoscalar sectors are compared to previous $N_f=2$ results and their phenomenological values. Finally, the strategy for extending simulations to $N_f=2+1+1$ is outlined.
