Development of a Trigger for Proton-Charm Femtoscopy with ALICE for the LHC Run3

In this CERN Summer Student project, the feasibility of a proton-charm hadron trigger for femtoscopic studies in proton-proton collisions with ALICE has been investigated for the upcoming LHC Run3. After a short introduction to femtoscopy and the charm hadron selection, this report presents the results concerning the impact of the topological charm hadron selections on the trigger. The studies have been performed with Monte Carlo simulations of the ALICE detector using the PYTHIA generator as an input. Lastly, the implementation of the trigger in the ALICE Run3 analysis framework O2 is briefly discussed.
