Abstract

The frequently discussed strongly interacting gauge theory with a fermion flavor doublet in the two-index symmetric (sextet) representation of the SU(3) color gauge group is investigated [1]. The chiral condensate and the mass spectrum are consistent with chiral symmetry breaking (cSB) at vanishing fermion mass. In contrast, sextet fermion mass deformations of spectral properties are not consistent with leading conformal scaling behavior near the critical surface of a conformal theory. A recent paper [2] which could not resolve the conformal fixed point of the gauge coupling from the slowly walking scenario of a very small nearly vanishing b-function is not in conflict with cSB reported here. A light Higgs impostor could emerge as the dilaton from spontaneous symmetry breaking of scale invariance or, without the dilaton mechanism, as a composite state.
