  Static quark-antiquark states in QCD, at finite quark separation, have a
spectrum of metastable states corresponding to string-like excitations of the
gauge field. In this article I suggest that there may also exist an excitation
spectrum of heavy fermions in some gauge Higgs theories deep in the Higgs
phase. In this situation there are no color electric flux tubes connecting
quarks with antiquarks. There may, nonetheless, exist stable excitations of the
bosonic fields surrounding an isolated fermion, below the particle production
threshold. I present numerical evidence indicating the existence of such
excitations in an SU(3) gauge Higgs theory, with the scalar field in the
fundamental representation of the gauge group.
