W-Tagging/B-Veto in SUSY search for squarks and gluinos in final states with missing transverse energy, jets, and one isolated lepton at ATLAS

This report recapitulates my stay at CERN as a Summer Student in a 13-week period from June 29 to September 25 in 2015. During that time, I was part of the CERN ATLAS Supersymmetry working group and working on a project exploiting W-tagging and B-veto techniques for the search for squarks and gluinos in final states with missing transverse energy, jets, and one isolated lepton. In this report, I will summarize my project and present results and conclusions. Apart from that, I will also write about my experience with the Summer Student lectures, the social aspects and the CERN Summer School in general.
