Under the assumption of a longitudinal, boost invariant expansion of the plasma, we obtain analytical expressions for the correlations from the quark-gluon plasma phase. A $3+1$ dimensional expansion of the plasma along with a first order phase transition to hadrons is next considered, and, leads to a source with two characteristic lifetimes, one for the quark-gluon plasma phase, and the other for the longer lived mixed phase. This may even help us to {\\em experimentally} determine the order of the phase transition.", "revisions": [ { "version": "v1", "updated": "1993-11-10T19:21:38.000Z" } ], "analyses": { "keywords": [ "high energy photons", "mixed phase", "quark-gluon plasma phase", "ultra-relativistic heavy ion collisions", "first order phase transition" ], "tags": [ "journal article" ], "note": { "typesetting": "LaTeX", "pages": 11, "language": "en", "license": "arXiv", "status": "editable", "inspire": 360258 } } }
