摘要
We suggest that the "new form of matter" found just above T-c by the Relativistic Heavy Ion Collider is made up of tightly bound quark-antiquark pairs, essentially 32 chirally restored (more precisely, nearly massless) mesons of the quantum numbers of pi, sigma, rho, and a(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 T-c just as they do from below T-c as predicted by the vector manifestation of hidden local symmetry. This could explain the rapid rise in entropy up to T-c found in LGS calculations. We argue that how the dynamics work can be understood from the behavior of the hard and soft glue.
