Measurement of the top quark pair production cross section in dilepton final states containing one tau lepton in pp collisions at root s=13 TeV

The cross section of top quark pair production is measured in the t¯t → (`ν` )(τhντ )bb final state, where ¯ τh refers to the hadronic decays of the τ lepton, and ` is either an electron or a muon. The data sample corresponds to an integrated luminosity of 35.9 fb−1 collected in proton-proton...
