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.

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 ...
Jet-Fragmentation Transverse Momentum from Di-Hadrons Correlations in √s_NN = 5.02 TeV Pb-Pb Collisions Gilbert, Alexander Kevin (2020)The jets’ transverse structure in Pb-Pb collision system has been studied with jet-fragmentation transverse momentum (jT ) distribution. The data were collected from ALICE experiment at LHC in energy √s_NN = 5.02 TeV per ...
Temperature dependence of η/s of strongly interacting matter : effects of the equation of state and the parametric form of (η/s)(T) Auvinen, Jussi; Eskola, Kari J.; Huovinen, Pasi; Niemi, Harri; Paatelainen, Risto; Petreczky, Péter (American Physical Society (APS), 2020)We investigate the temperature dependence of the shear viscosity to entropy density ratio η/s using a piecewise linear parametrization. To determine the optimal values of the parameters and the associated uncertainties, ...

Event-by-event fluctuations in a perturbative QCD + saturation + hydrodynamics model: Determining QCD matter shear viscosity in ultrarelativistic heavy-ion collisions Niemi, Harri; Eskola, Kari; Paatelainen, Risto (American Physical Society, 2016)We introduce an event-by-event perturbative-QCD + saturation + hydro (“EKRT”) framework for ultrarelativistic heavy-ion collisions, where we compute the produced fluctuating QCD-matter energy densities from next-to-leading-order ...
