Utilizing high-p⊥ theory and data to constrain the initial stages of quark-gluon plasma

Theory of the Quark-Gluon Plasma

Chern-Simons theory and the quark-gluon plasma.

The generating functional for hard thermal loops in Quantum Chromodynamics is important in setting up a resummed thermal perturbation theory, so that all terms of a given order in the coupling constant can be consistently taken into account. It is also the functional which leads to a gauge invariant description of Debye screening and plasma waves in the quark-gluon plasma. We have recently show...

Toward the theory of strongly coupled Quark-Gluon Plasma (sQGP)

We review recent progress toward understanding of sQGP. The phenomenological part includes discussion of elliptic and conical flows at RHIC. Then we proceed to first quantum mechanical studies of manybody states at T > Tc, the “polymeric chains” q̄.g.g...q and baryons. A new model for sQGP is a classical dynamical system, in which color vector is changed via the Wong equation. First Molecular Dy...

Theory of Quark - Gluon Plasma and Phase Transition

Nonperturbative picture of strong interacting quark-gluon plasma is given based on the systematic Field Correlator Method. Equation of state, phase transition in density-temperature plane is derived and compared to lattice data as well as subsequent thermodynamical quantities of QGP.

The Energy of the High-temperature Quark-gluon Plasma

For the quark-gluon plasma, an energy-momentum tensor is found corresponding to the high-temperature Braaten-Pisarski effective action. The tensor is found by considering the interaction of the plasma with a weak gravitational field and the positivity of the energy is studied. In addition, the complete effective action in curved spacetime is written down. 1 Introduction The high-temperature pro...
