Measurement of the inclusive top-pair production cross section at $ \sqrt{s}$ = 13 TeV with the CMS detector in the dilepton final state

The inclusive cross section for top-quark pair production is measured in proton-proton collisions at a centre-of-mass energy of 13 TeV with the CMS experiment at the LHC using the data samples collected in 2015 and the first data collected in 2016. The measurement is performed with events containing an opposite charge electron-muon pair and at least 2 jets, one of which is identified asa b-jet. Background estimates are obtained using data driven techniques as much as possible anda event counting is used for the final measurement.
