Magnetic field dependence of dielectron measurements with ALICE 3 — •Zafar Momtaz for the ALICE Germany collaboration — Institut für Kernphysik, Goethe-Universität Frankfurt

Ultra-relativistic heavy-ion collisions are used to study strongly interacting matter under extreme conditions, i.e. high temperature and energy density, where a deconfined state of quarks and gluons is formed and chiral symmetry is expected to be restored. At the LHC, a next-generation heavy-ion experiment, called ALICE 3, is planned beyond the 2030s to address the remaining fundamental questions still open. In particular, ALICE 3 should enable precise measurements of the temperature evolution of the quark-gluon plasma created in heavy-ion collisions via dielectron analyses. Moreover it should allow us to study the mechanisms of chiral symmetry restoration from the spectrum of dielectron created in the medium in the vicinity of the transition temperature via the spectral function of the ρ - meson. In order to achieve these physics goals, the ALICE 3 detector setup would include an ultra-light tracker, covering the pseudorapidity range of of |η| < 4 and installed within a superconducting magnet system.

This poster will show the expected dielectron measurement performance with ALICE 3 for different magnetic fields. In particular, we will focus on the tracking and electron identification efficiencies for different detector configurations and explain how they influence the predicted uncertainties of the temperature measurements of the fireball.
