Search for Excited Quark Resonances in the Photon+Jet Invariant Mass Spectrum at 13 TeV

摘要

44.1 Introduction This document reports a search for compositeness of quarks using the data collected by the CMS experiment [1] at the CERN LHC. The standard model, despite its remarkable success, has not been able to address some of the key questions of the particle physics. The increase in collision energy at the LHC and improvement in detector technology make it possible to search for extensions of the standard model. Several of these extensions suggest quark substructure [2].
