Abstract

As part of an ongoing programme to study Sp(2N) gauge theories as potential realisations of composite Higgs models, we consider the case of Sp(4) on the lattice, both as a pure gauge theory, and with two Dirac fermion flavors in the fundamental representation. In order to compare results between these two cases and maintain control of lattice artefacts, we make use of the gradient flow to set the scale of the simulations. We present some technical aspects of the simulations, including preliminary results for the scale setting in the two cases and results for the topological charge history.
