Deconfinement and Quarkonium Dissociation

摘要

The study of quarkonium spectra provides in statistical QCD an unambiguous method to determine temperature or energy density of strongly interacting matter. Whether it can also do that in nuclear collisions remains another matter. We have not addressed here 1. whether nuclear collisions produce thermal media, 2. possible initial state dissociation of quarkonia (parton percolation/saturation), 3. the experimental results and their analyis, including the determination of pre-resonance nuclear absorption or the information obtained from transverse momentum spectra.There is much interesting work left to do...
