Formulation of Vector Manifestation in Hot and / or Dense Matter
The vector manifestation (VM) was proposed as a novel manifestation of chiral symmetry in which the massless vector meson becomes the chiral partner of pion. In this write-up, I briefly summarize the following main ingredients to formulate the VM in hot and/or dense matter: Effective field theory (EFT) based on the hidden local symmetry; Wilsonian matching between the EFT and QCD; Intrinsic the...
متن کاملVector Manifestation in Hot And/or Dense Matter * )
In this talk I summarize main features of the vector manifestation (VM) which was recently proposed as a novel manifestation of the Wigner realization of chiral symmetry in which the symmetry is restored at the critical point by the massless degenerate pion (and its flavor partners) and the ρ meson (and its flavor partners) as the chiral partner. I show how the VM is realized in hot and dense Q...
متن کاملVector Manifestation in Hot Matter
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 ρ meson becomes massless degenerate with π as the chiral partner. This is done by including, in addition to the hadronic thermal effects due to the πand ρ-loops, the intrinsic temperature depe...
متن کاملHidden Local Symmetry and the Vector Manifestation of Chiral Symmetry in Hot and/or Dense Matter
The emergence and importance of hidden local symmetry in the structure of hadrons under extreme conditions is discussed. The topics covered are the potentially important role played by an infinite tower of vector mesons encoded in holographic dual QCD (or AdS/QCD) in chiral dynamics of mesons and baryons, in the vector dominance and its violation in EW response functions and the presence of the...
متن کاملVector Manifestation in Hot Matter and Violation of Vector Dominance
We summarize main mechanisms to realize the vector manifestation (VM), in which the massless vector meson becomes the chiral partner of pion, at the critical temperature in hot QCD within the framework of the model based on the hidden local symmetry. Then, we show a recent analysis on the direct photon-π-π coupling which measures the validity of the vector dominance (VD) of the electromagnetic ...
