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 [1-3]. In previous studies  the chiral condensate and the mass spectrum were shown to be consistent with chiral symmetry breaking (cSB) at vanishing fermion mass. The recently reported b -function  is not inconsistent with this observation, suggesting that the model is very close to the conformal window and a light "Higgs impostor" could emerge as a composite state. In this work we describe the methodology and preliminary results of studying the emergence of the light composite scalar with 0++ quantum numbers.
