AbstraktAbstract
In summer 2022, the first LHC Run-3 proton-proton collision data were recorded with the ATLAS central detector and the ATLAS Forward Proton (AFP) detectors. The first analysis of this new data was performed. Efficiencies and resolutions for the Time-of-Flight (ToF) detector were studied with different methods. In addition, these performance studies of the ToF data included the proton-proton vertex reconstruction using matching of ToF and central ATLAS vertex position. After a calibration, a preliminary resolution of the vertex reconstruction was determined with a low-mu ATLAS run. Based on selected di-photon events, vertex reconstruction studies were conducted using simulated and recorded 2017 data. Different techniques of central ATLAS vertex reconstruction were compared. Using one technique, a di-photon vertex reconstruction was performed with 2022 data. The potential of ToF data for an improved vertex reconstruction and thus reduction of background in an Axion-Like-Particle search using AFP data has been demonstrated.
