First Measurement of the Running of the Top Quark Mass Cham : Springer International Publishing AG,c2022 9783030903756 Introduction -- The Standard Model of Particle Physics and the Top Quark -- The LHC and the CMS Detector -- Event Reconstruction in CMS -- Appendices.In this thesis, the first measurement of the running of the top quark mass is presented. This is a fundamental quantum effect that had never been studied before. Any deviation from the expected behaviour can be interpreted as a hint of the presence of physics beyond the Standard Model. All relevant aspects of the analysis are extensively described and documented. This thesis also describes a simultaneous measurement of the inclusive top quark-antiquark production cross section and the top quark mass in the simulation. The measured cross section is also used to precisely determine the values of the top quark mass and the strong coupling constant by comparing to state-of-the-art theoretical predictions. All the theoretical and experimental aspects relevant to the results presented in this thesis are discussed in the initial chapters in a concise but complete way, which makes the material accessible to a wider audience.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5061Particles (Nuclear physics)Quantum field theoryQuantitative researchParticles (Nuclear physics)Elementary Particles, Quantum Field TheoryData Analysis and Big DataParticle PhysicsParticles (Nuclear physics)Quantum field theory.Quantitative research.Particles (Nuclear physics)Elementary Particles, Quantum Field Theory.Data Analysis and Big Data.Particle Physics.531.140287539.72167Defranchis Matteo M.1075248MiAaPQMiAaPQMiAaPQ9910520078703321First Measurement of the Running of the Top Quark Mass2584237UNINA
