Toward TeV Conformality

We study the chiral properties of an SU(3) gauge theory with N_f massless Dirac fermions in the fundamental representation when N_f is increased from 2 to 6. For N_f=2, our lattice simulations lead to a value of ⟨ψ¯ψ⟩/F³, where F is the Nambu-Goldstone-boson decay constant and ⟨ψ¯ψ⟩ is the chiral condensate, which agrees with the measured QCD value. For N_f=6, this ratio shows significant enhancement, presaging an even larger enhancement anticipated as N_f increases further, toward the critical value for transition from confinement to infrared conformality.
