Reconstruction of hadronic showers in the SND@LHC experiment

This thesis is about the SND@LHC experiment, a compact, standalone detector located in the TI18 tunnel (480 m downstream of the ATLAS interaction point). The experiment is designed to detect and identify neutrinos of all three flavors, produced in LHC proton-proton collisions in the pseudorapidity region 7.2 < η < 8.4, and to study, for the first time in laboratory, neutrino interactions in the energy range between 300 GeV and 1 TeV. In this thesis, I focused on studying the reconstruction of hadronic showers using test beam data to evaluate the accuracy and sensitivity achievable by the experiment in locating hadronic showers. The method achieved an angular resolution of approximately 30 mRad. The reconstruction of hadronic shower directions is relevant for determining the energy of the incoming neutrino. All analyses were carried out using C++ code developed specifically for this purpose.
