An Exploratory Study of LHCf-triggered Events at ATLAS

The LHCf detector at the LHC in Geneva was conceived to put constrains on hadronic interaction models which are used in cosmic ray air shower simulations. Detecting the same interactions as ATLAS does in the central region in the very forward region, a common data taking operation was a logical choice. The complementarity of both detectors presents a unique opportunity to significantly improve hadronic interaction models. This thesis constitutes a proof of concept that such a common data taking is possible. Utilizing commonly recorded datasets during the 2013 proton-lead run at 5.02 TeV, we will demonstrate the successful offline matching of events from the datasets from both experiments. Moreover, a preliminary exploratory data analysis is conducted - exhibiting the benefit of the ATLAS-LHCf collaboration to the amelioration of hadronic interaction models when exploiting data collected during the 2015 proton-proton run at pp 13 TeV.
