Low-Mass Dielectron Production in Heavy-Ion Collisions at LHC Energies
Sebastian Scheid(Universität Frankfurt)
The measurement of dielectrons is a fundamental piece in the understanding of hot and dense matter produced in ultra-relativistic heavy-ion collisions. The dielectron spectra yield information that pierces the veil of final-state hadronic interactions and gives direct access to the early phases of the collision.
In this seminar, I will give an overview of the dielectron measurements at ultra-relativistic energies achieved in recent years. I will focus on the measurements performed by the ALICE collaboration but will also include measurements at lower energies.
A main part of the presentation will be the discussion of prospects for measurements that will be possible with the latest as well as future upgrades of the ALICE experiment.
