Description
In the context of possible dilaton behavior in near conformal gauge theories, it has recently been proposed that a parametrized potential $V_\Delta$, interpolating between two limiting forms, might effectively describe the light particle spectrum. We tested two models, namely SU(3) gauge theory with $N_f = 8$ fermions in the fundamental rep or $N_f = 2$ fermions in the sextet rep, against this hypothesis. The data are found to be consistent with the $V_\Delta$ potential across a broad parametrization range, in contrast to claims by other groups that the $N_f = 8$ model prefers one limit over the other.
