Scalar bosons composed of a pair of chiral fermions in a non-confining potential have an effective Yukawa coupling, g, to free external chiral fermions. At large distance a Feynman loop of external fermions generates a scale invariant potential, Vloop∝ -g2/r2, which acts on valence fermions for separation ρ=2r. This generally forces the s-wave ground state to deform to a static, zero mass, configuration, and for slowly running, perturbative g, a large external "shroud" wave-function forms. This is related to old results of Landau and Lifshitz in quantum mechanics. The massless composite scalar boson ground state is then an extended object. Infra-red effects can generate a small mass for the system. This points to a perturbative BEH-boson composed of top and anti-top quarks and a novel dynamical mechanism for spontaneous electroweak symmetry breaking.
