Description

We study quark and gluon production from an expanding strong color electric flux tube. Firstly, we derive a set of linear equations for quantum fluctuations by employing a mean-field approximation on top of the strong color electric flux tube, which describes the particle production and its backreaction on the flux tube. Second, we carry out numerical simulations and discuss how the flux tube decay through the quark and gluon production to form a quark-gluon plasma. In particular, we discuss the time evolution of (i) the phase space density of produced particles; (ii) the energy balance between the produced particles and the color flux tube; and (iii) the transverse and longitudinal pressure of the system, i.e., the degree of isotropization of the system.
