The Quark gluon plasma is a matter which consists from a weakly coupled quarks and gluons and it can only be created on extreme temperatures or pressures. After QGP cools down it experiences phase transition to the hadron gas. The evolution of QGP and hadron gas can be modeled using the relativistic hydrodynamics, which is effective theory describing dynamics of the fluids. In this thesis we are particularly interested about effects of the bulk viscosity in Pb+Pb collisions with $\\sqrt{s_{NN}}$ = 2.76 TeV. Initial state for hydrodynamic evolution was calculated using the EKRT-model and freeze-out was done using Cooper-Frye procedure. We found out that the bulk viscosity caused expansion of the system to slow down which evidently decreased average transverse momentum of the final state particles.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2019-12-19T11:45:50Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2019-12-19T11:45:50Z (GMT).
