Query: Interacting color strings as the origin of the liquid behavior of the
  quark-gluon plasma   We study the radial distribution function of the color sources (strings)
formed in hadronic collisions and the requirements to obtain a liquid. As a
repulsive interaction is needed, we incorporate a concentric core in the
strings as well as the probability that a string allows core-core overlaps. We
find systems where the difference between the gas-liquid and
confined-deconfined phase transition temperatures is small. This explains the
experimentally observed liquid behavior of the quark-gluon plasma above the
confined-deconfined transition temperature.
