Description

We describe our recent lattice study of SU(4) gauge theory with dynamical Wilson-clover fermions in the fundamental and sextet representations. In this theory, a unique type of baryon consists of quarks in both representations. The spectrum of these "chimera baryons" turns out to have enlightening interpretations in terms of large-N expansion and the non-relativistic quark model. We also discuss the relevance of these results for so-called "partially composite" models of physics beyond the Standard Model.
