Abstract

We present a concise review of quark-gluon plasma formation in heavy-ions collisions within the holographic approach. In particular, we discuss how to get the total multiplicity in heavy ions collision to fit the recent experimental data. We also discuss theoretical estimations of time formation of QGP in heavy ions collision and show that different observables can give the different times of QGP formation.

Summary

Introduction

It is my pleasure to give a talk here. I would like to thanks the organizers for invitation. The subject of my talk is holography description of quark-gluon plasma (QGP) formation in heavy-ions collisions (HIC). I’ll start from the physical picture of formation of QGP in HIC. I’ll remind the raisons to use dual approach to physical problems related with QGP. As to holographic approach to QGP there are two options:. There is considerable progress in applications of holography to static properties of QGP [1] The main part of the talk will be devoted to discussion of the holographic description of the process of formation of QGP. The goal will be to fit experimental date related with multiplicity and thermalization time in heavy ions collisions. One can find the holographic description of QGP formation in [2, 3]
