Vector Manifestation in Hot Matter

Abstract

Based on the hidden local symmetry (HLS) Lagrangian as an effective field theory of QCD, we find that the chiral symmetry restoration for hot QCD can be realized through the Vector Manifestation where the rho meson becomes massless degenerate with pi as the chiral partner. This is done by including, in addition to the hadronic thermal effects due to the pi- and rho-loops, the intrinsic temperature dependences of the parameters of the HLS Lagrangian through the matching of the HLS with the underlying QCD.

6 pages, sectioned, estimation of the critical temperature is changed with one table and one reference added. Several parts are changed for clarification of our approach. This is the version to appear in Phys. Lett. B
