Analysis of Emulsion RUN0 Data of the SND@LHC Experiment at the CERN-LHC

SND@LHC is a compact and stand-alone experiment that covers the pseudo-rapidity region of 7.2 < $\eta$ < 8.4, inaccessible to the other experiments at the Large Hadron Collider (LHC). It has the potential to make significant contributions to neutrino physics in a previously unexplored high-energy region between 350 GeV and 10 TeV and the physics beyond the Standard Model. The SND@LHC "Emulsion RUN0" setup was designed to test data reconstruction processes' performance, including emulsion scanning and subsequent reconstruction steps. Through the use of this test setup, the experiment can determine the efficiency and precision of linking, alignment, tracking, and vertexing algorithms. In this thesis work, the Emulsion RUN0 Data is analyzed, and new selection criteria on the track and vertex reconstruction are applied to improve the tracking and vertexing. A significant reduction in the number of false tracks and vertices was obtained while improving the vertex quality in terms of impact parameter and multiplicity distributions.
