Content

We present preliminary results from dynamical simulations of QCD in isolation, as well as QCD coupled to QED, with C boundary conditions. In finite volume, the use of C boundary conditions allows for a gauge invariant and local formulation of QED without zero modes

We start with an overview of the simulation code and its features. In particular we discuss the implementation of the C* boundary conditions and some of the associated complications. These include the need for a modified fermion representation, the use of rational approximations in the action, and the construction of gauge-invariant interpolating operators for charged states.

We continue by presenting results from simulations of QCD in isolation. We are currently producing ensembles with CLS parameters using periodic and C* boundary conditions in space, in order to show that we are able to reproduce known results and to compare the two setups. At the moment we are only considering simple quantities such as meson states and gradient flow observables. We conclude with some experiences and preliminary results from the simulations of QCD coupled to QED.
