QGP and CGC

  1. Jun 4, 2008 #1
    Dear PFers,

    could somebody provide an update on the searches for quark gluon plasma, the color glass condensate interpretation, and/or their conceptual basis ? I have found a few big documents, if somebody knows where to find the latest review it would be most welcome. I would like a preview of the several hundred pages I am embarking on :smile:

    Thank you very much in advance

    Hi!
    I like to look at the papers presented at the conferences and then to look at the papers that they have published for more info.
    Have you checked out http://www.pascos07.org/programme/

    The latest presentation is at Perimeter Institute
    http://pirsa.org/
    “Click” on “catch up” and you will see a list of their latest conference papers.
    Read Bill Zajc’s paper first.

    Quark Gluon Plasma at RHIC (and in QCD and String Theory)

    I will be putting the links in my blog ... if it comes back online.
    What papers are you reading?

    Thanks for the links, they were very intersting
    working on "Hunting the QGP", BNL-73847-2005 (Results from the first 3 years at RHIC, formal report). I was wondering if there was some more recent "official" assessments.

    You have probably found

    ------
    As said, in the paper that you are reading,
    "It is now generally thought that the early universe was initially in a QGP state until its energy density had decreased sufficiently, as a result of the expansion of the universe, that it could make the transition to ordinary (confined) matter."
    -------
    I find it strange that there is so little discussion, on this forum, of what can only be "cutting edge". The models that "THEY" come up with have direct input into the models being developed by beyond the standard model and cosmology.

    I know that there are all kinds of people that read this thread that know a lot more than me.

    Could I get an input? ...

    p.272 (265)
    The phase diagram of bulk thermally equilibrated strongly interacting matter should be described by QCD. At sufficiently high temperature one must expect hadrons to \melt", deconfining quarks and gluons. The exposure of new (color) degrees of freedom would then be manifested by a rapid increase in entropy density, hence in pressure, with increasing temperature, and by a consequent change in the equation of state (EOS). In the limit where the deconfined quarks and gluons are non-interacting, and the quarks are massless, the (Stefan-Boltzmann) pressure PSB of this partonic state, as a function of temperature T at zero chemical potential (i.e., zero net quark density), would be simply determined by the number of degrees of freedom [2]:

    Have we got evidence that there is mass in a quark-gluon plasma?
    It appears that the models being tried leave mass out and that mass is a result of confinement.
