Baryons and Skyrmions in QCD with quarks in higher representations
Baryons and Skyrmions in QCD with quarks in higher representations
We study the baryonic sector of QCD with quarks in the two-index symmetric or antisymmetric representation. The minimal gauge invariant state that carries baryon number cannot be identified with the Skyrmion of the low-energy chiral effective Lagrangian. Mass, statistics, and baryon number do not match. We carefully investigate the properties …
