Measurement of the top quark pair production cross section in proton-proton collisions at 13 TeV with the CMS detector

Abstract

ABSTRACT: The top quark pair production is one of the dominant processes at the Large Hadron Collider (LHC). Properties of the top quark are measured with high precision and also is one of the main backgrounds for the search of new physics at the LHC. In this project we present the measurement of the production cross section of a pair of top quarks using the final di-lepton decay channel. It has been used data collected by the Compact Muon Solenoid (CMS) detector, at a center-of-mass energy of 13 TeV and an integrated luminosity of 35.8 pb−1.
