Abstract

We suggest that the "new form of matter" found just above TcT_c by RHIC is made up of tightly bound quark-antiquark pairs, essentially 32 chirally restored (more precisely, nearly massless) mesons of the quantum numbers of π\pi, σ\sigma, ρ\rho and a1a_1. Taking the results of lattice gauge simulations (LGS) for the color Coulomb potential from the work of the Bielefeld group and feeding this into a relativistic two-body code, after modifying the heavy-quark lattice results so as to include the velocity-velocity interaction, all ground-state eigenvalues of the 32 mesons go to zero at TcT_c just as they do from below TcT_c as predicted by the vector manifestation (VM in short) of hidden local symmetry. This could explain the rapid rise in entropy up to TcT_c found in LGS calculations. We argue that how the dynamics work can be understood from the behavior of the hard and soft glue.
