Thermal rho’s in the quark-gluon plasma
I discuss different models which predict changes in the mass of the thermal ρ field. I emphasize that while the predictions are strongly model dependent, nevertheless substantial shifts in the thermal ρ mass are expected to occur at the point of phase transition. As long as the thermal ρ peak does not become too broad, this should provide a striking signature of the existence of a phase transit...
متن کاملHard Thermal Loops , Quark - Gluon Plasma Response
I outline various derivations of the non-Abelian Kubo equation, which governs the response of a quark-gluon plasma to hard thermal perturbations. In the static case, it is proven that gauge theories do not support hard thermal solitons. Explicit solutions are constructed within an SU (2) Ansatz and they are shown to support the general result. The time-dependent problem, i.e., non-Abelian plasm...
متن کاملThe Quark-Gluon Plasma: Collective Dynamics and Hard Thermal Loops
We present a unified description of the high temperature phase of QCD, the so-called quark-gluon plasma, in a regime where the effective gauge coupling g is sufficiently small to allow for weak coupling calculations. The main focuss is the construction of the effective theory for the collective excitations which develop at a typical scale gT , which is well separated from the typical energy of ...
متن کاملTowards the Quark-Gluon Plasma
We discuss recent experimental results in the field of ultra-relativistic nuclear collisions. The emerging “picture” is a collectively expanding, initially hot and dense fireball in which strangenessand low-mass di-lepton pair production are enhanced and J/Ψ production is suppressed compared to expectations from nucleon-nucleon collisions. It is argued that, taken together, these data provide c...
متن کاملsignal the quark gluon plasma ?
We first review the production and the possible chemical equilibration of strange particles at CERN-SPS energies within a microscopic hadronic transport calculation. It is shown in particular that the strange quarks are produced initially via string excitations in the primary, secondary and ternary interactions. We then further elaborate on a recent idea of antihyperon production by multi-meson...
