Proceedings of the IFJ PAN Particle Physics Summer Student Alumni Conference 2022

IFJ PAN PPSS Alumni Conference is organized by the Institute of Nuclear Physics Polish Academy of Sciences (IFJ PAN). It is addressed to: participants of previous editions of Particle Physics Summer Student Programme, attendees of current PPSS edition and students interested in cooperation with IFJ PAN. First IFJ PAN Particle Physics Summer Student Alumni Conference was held on 9-10 July 2022, with topic focused on, but not restricted to, high energy physics.

From Wigner distributions of photons to dilepton production in semicentral heavy ion collisions

We present a formalism how to calculate differential distributions for dilepton production in semicentral heavy ion collisions. In this new approach, the differential cross section is calculated using the complete polarization density matrix of photons resulting from the Wigner distribution formalism. The formalism is used to calculate different distributions of the invariant mass, dilepton transverse momentum and acoplanarity for different regions of centrality. The results of the calculation are compared with recent experimental data. We also study the contribution from different parts of impact parameter space.
