We calculate the one- and two-point correlation functions of the energy density and the divergence of the Chern-Simons current in the nonequilibrium glasma state formed in a high-energy nuclear collision. We show that the latter depends on the difference of the total and linearly polarized gluon transverse momentum distributions. Since the divergence of the Chern-Simons current provides the source of axial charge, we infer information about the statistical properties of axial charge production at early times. We further develop a simple phenomenological model to characterize axial charge distributions in terms of distributions of the energy density.

Evolution of initial stage fluctuations in the glasma
Guerrero-Rodríguez, Pablo; Lappi, Tuomas (American Physical Society, 2021)We perform a calculation of the one- and two-point correlation functions of energy density and axial charge deposited in the glasma in the initial stage of a heavy ion collision at finite proper time. We do this by describing ... -

Spectral function for overoccupied gluodynamics from real-time lattice simulations
Boguslavski, Kirill; Kurkela, A.; Lappi, Tuomas; Peuron, Jarkko (American Physical Society, 2018)We study the spectral properties of a highly occupied non-Abelian nonequilibrium plasma appearing ubiquitously in weak coupling descriptions of QCD matter. The spectral function of this far-fromequilibrium plasma is ...
