Abstract

Investigation of composite Higgs models (CHMs) is of importance in contemporary particle physics. In this article, we present lattice computations of the chimera baryon masses in (4) gauge theory with two and three Dirac flavours of hyperquarks (beyond the Standard Model fermions coupled to the (4)...
