Asymptotic Freedom and Color Superconductivity in Dense Quark Matter

  • Steven C. Frautschi
Part of the Ettore Majorana International Science Series book series (EMISS, volume 2)


In the present talk I shall deal with densities much higher than nuclear - densities which, as far as we know, were achieved only in the very early stages of the big bang. I shall review two issues:
  1. i)

    The current view that QCD predicts an approximately free quark-gluon gas phase at high densities and temperatures, which is incompatible with the kind of non-perturbative confinement effects that would be needed to yield a limiting Hagedorn temperature at high densities.

  2. ii)

    The recent suggestion of my student, Bertrand Barroisl1, that QCD leads to a different kind of non-perturbative phase, analogous to superconductivity, at high densities and low temperatures.
