We also study the characteristic momentum scale and\noccupation number distributions. We determine the gluon Debye screening\nmass by performing linear fits into the gluon dispersion relation in the low\nmomentum regime. We compare the result to the one obtained using a formula\nderived from thermal field theory.\nWe start by quickly reviewing the heavy-ion physics context for this work.\nThen we quickly recap the classical Yang-Mills theory in the continuum and on\nthe lattice.\nWe will go through a Fourier accelerated Coulomb gauge fixing procedure in\ndetail in the continuum theory and on the lattice. This will be an essential part\nof this work, as some observables we use are meaningful only in the Coulomb\ngauge.\nThen we introduce the gauge invariant and gauge dependent observables\nand the initial conditions used. In this work we find evidence for the existence\nof a non-zero Debye screening mass at high occupation numbers and late\ndimensionless times. We observe that the Debye mass gets bigger at higher\noccupation numbers as expected from thermal field theory.\nAccording to the thermal field theory the gluon Debye mass is also time\ndependent through its occupation number distribution dependence. Due to low\nstatistics we cannot draw any firm conclusions about the time dependence of\nthe Debye screening mass.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Jarkko Peuron (jatapeur) on 2014-09-05 09:08:16.846010.
