Thermalization of Color Gauge Fields in High Energy Heavy Ion Collisions

Abstract

We discuss quantum mechanical decay of color magnetic field generated initially at high energy heavy ion collisions. It is caused by Nielsen-Olesen unstable modes and is accomplished possibly in a period $<1$fm/c. We show that the decay products, i.e. incoherent gluons may be thermalized in a sufficiently short period ($<1$fm/c). The precise determination of the period is made by calculating two point function of the color magnetic field in a model of color glass condensate.
