In the search for physics beyond the Standard Model, a detailed understanding of the Higgs boson properties is a crucial component. This exercise aims to give an overview of different analysis aspects in the context of Higgs physics at the CMS experiment. Specifically, we will discuss challenges and requirements needed for the selection of objects in signal and background events as well as the...
This section is focused on jets, which are a powerful tool to constrain the strong coupling constant alphaS, the parton distribution functions (PDFs) and to search for new physics. During the exercise, the students will go through the main steps of jet analyses up to the cross section extraction with a special focus on the trigger, jet energy corrections, pileup, and unfolding procedure. In...
During the exercise, the students will go through the main steps of dimuon analyses up to the branching fraction extraction, checking at event level the impact of the standard corrections at CMS. In the exercise, ROOT and C++ will be used.
This analysis is a generic search for new physics targeting final states with one or more top quarks. It is motivated by models of R-parity conserving Supersymmetry (SUSY) that assume the existence of additional elementary particles not included in the Standard Model (SM). In the simplest case, there is one supersymmetric partner-particle for each Standard Model SM particle. The existence of...
This exercise will perform a measurement of the top quark pair production cross section at a center of mass energy of 13.6 TeV, using data recorded by CMS in 2022. Based on a simplified version of the first CMS publication from LHC Run 3, the measurement will focus on the dilepton decay channels. A modern python-based framework will be used, with some dependence on the scikit-HEP package...
