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

During the Long Shutdown 4 of the Large Hadron Collider, ALICE will upgrade its complete detector to address new physics cases with unprecedented resolution and higher interaction rates, called ALICE 3. The Forward Conversion Tracker (FCT), located in the forward direction, will measure the photon spectrum predicted by Low’s theorem in proton-proton collisions at √s = 14 TeV.

The focus of this talk will be on the status of the simulation studies of the FCT. The O2 framework of ALICE allows for detailed, full simulations of proton-proton collisions including transportation through the detector setup of ALICE 3. The background bremsstrahlung generated by charged particles passing through material in front of the FCT is a major challenge for this study and strategies to reduce this background will be presented. One of the major strategies is to provide electron particle identification in the region of the FCT, and the other major strategy is to construct a conical beam pipe which comes with its own challenges.
