Phys. Rev. Lett. 83, 3374–3377 (1999)Conformal Phase Transition and Fate of the Hidden Local Symmetry in Large Nf QCDReceived 21 June 1999; published in the issue dated 25 October 1999 It is observed that the hidden local symmetry (HLS) for vector mesons in ordinary QCD with smaller Nf plays the role of the “Higgsed magnetic gauge symmetry” for the Seiberg duality in SUSY QCD. For large Nf where the conformal phase transition with chiral restoration and deconfinement is expected to take place, we find that the HLS model also exhibits chiral restoration by loop corrections (including the quadratic divergence) in a manner similar to that in the CPN-1 model, provided that the bare HLS Lagrangian respects Georgi's vector limit at a certain Nf ( ≈7). © 1999 The American Physical Society URL:
