Simulation studies for the Forward Conversion Tracker of ALICE 3 in run 5 — •Casper van Veen for the ALICE Germany collaboration — Physikalisches Institut Heidelberg, Heidelberg, Germany

During the Long Shutdown 4 of the LHC (LS4), the ALICE experiment will be upgraded to ALICE 3. Along with an advanced silicon-based tracking system placed closer to the interaction point, ALICE 3 will also come equipped with a Forward Conversion Tracker (FCT) which will measure the transverse momentum of soft photons in the forward direction. In the soft photon regime, the bremsstrahlung spectrum can be computed in a model- and process-independent way by Low*s theorem. Most previous experiments have observed a soft photon excess on top of what is expected by Low*s theorem, but some did not observe this excess at all. This makes the experimental status of the existence of the excess unclear. The FCT, an array of silicon layers, will provide a way to measure these photons via the photon conversion method. The FCT will be provided with an unprecedented position resolution from these silicon trackers which should result in a very clean photon identification.

This talk will give an overview of the current studies of the FCT and provide an overview of the upcoming challenges.
