Abstract

We study the chiral condensate <ψˉψ><\bar{\psi} \psi> for an SU(3) gauge theory with NfN_f massless Dirac fermions in the fundamental representation when NfN_f is increased from 2 to 6. For Nf=2N_f=2, our lattice simulations of <ψˉψ>/F3<\bar{\psi} \psi >/F^3, where FF is the Nambu-Goldstone-boson decay constant, agree with the measured QCD value. For Nf=6N_f = 6, this ratio shows significant enhancement, presaging an even larger enhancement anticipated as NfN_f increases further, toward the critical value for transition from confinement to infrared conformality.
