Jet substructure at Future Circular Collider (FCC)

Title: Jet substructure at Future Circular Collider (FCC) Author: Tadeáš Petrů Department: Institute of Particle and Nuclear Physics Supervisor: Mgr. Jana Faltová, Ph.D., Institute of Particle and Nuclear Physics Abstract: Future Circular Collider (FCC-hh) is a proposed next-generation hadron collider with a center-of-mass energy of 100 TeV that could be built in CERN. This collider would serve both as a powerful discovery machine and also as a precision measurements machine. One of the challenges for detectors installed at FCC-hh would be an identification of highly boosted objects that subsequently decay hadronically. Within this thesis, we will study the ability of the calorime- ter system of the FCC-hh reference detector in distinguishing two-pronged jets from highly boosted W boson decays and one-pronged jets from light quarks. We will introduce several jet substructure variables and use them as inputs for multivariate analysis (boosted decision trees). Keywords: FCC, substructure, boosted objects ii
