Toward TeV Conformality

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