Initial state effects in p+Pb collisions at 5.02 TeV from the PHSD transport approach — •V.P. Konchakovski¹, W. Cassing¹, and V.D. Toneev² — ¹Institute for Theoretical Physics, University of Giessen, Giessen, Germany — ²Joint Institute for Nuclear Research, Dubna, Russia

We study initial state effects for different observables in p+Pb collisions at 5.02 TeV using event-by-event simulations within the Parton Hadron String Dynamics (PHSD) transport approach which incorporates both hadronic and partonic degrees of freedom and successfully describes heavy-ion collisions in a wide range of energies. We compare our results with data from the ALICE Collaboration as well as with calculations using Glauber and Color-Glass-Condensate (CGC) initial conditions and find that our results for fluctuations and distributions are close to the CGC assumptions. We additionally investigate the effects of color field fluctuations in the initial phase of the collision that emerge from the non-abelian dynamics of the chromo fields.
