Implications of Vector Manifestation in Hot and Dense Medium

Abstract:
The “vector manifestation (VM)" fixed-point scenario found in
Harada-Yamawaki hidden local symmetry effective theory makes a
prediction that hadrons do not interact or barely interact
as the fire-ball expands and cools from
Tc down toward the freeze-out temperature T freeze-out in
heavy ion collisions.
VM provide a simple prediction in terms of the vector manifestation
for the ρ0/π- ratio measured in peripheral collisions.
Vector manifestation also provides us a simple description of kaon
condensation by fluctuating around the fixed point identified to be
the chiral restoration point. It indicates that the critical density
for strangeness condensation is lower than the chiral symmetry
restoration density.
