# Measurement of the top quark pair production cross section in proton-proton collisions at $\sqrt{s}$ = 13 TeV

CMS Collaboration; Canelli, F; Chiochia, V; Kilminster, B; Robmann, P; et al (2016). Measurement of the top quark pair production cross section in proton-proton collisions at $\sqrt{s}$ = 13 TeV. Physical Review Letters, 116(5):052002.

## Abstract

The top quark pair production cross section is measured for the first time in proton-proton collisions at $\sqrt{s}$ = 13  TeV by the CMS experiment at the CERN LHC, using data corresponding to an integrated luminosity of 43  pb$^{−1}$. The measurement is performed by analyzing events with at least one electron and one muon of opposite charge, and at least two jets. The measured cross section is 746±58(stat)±53(syst)±36(lumi)  pb, in agreement with the expectation from the standard model.
