Abstract

The measurement of the inclusive Wt cross-section at 13 TeV is performed using 3.2 fb^-1 of proton--proton collision data collected by the ATLAS detector at the LHC in 2015. Events are required to have at least one jet and two opposite sign leptons. The cross section is measured to be σ_Wt = 94± 10(stat.)⁺²⁸_-22(syst.)± 2(lumi)pb, corresponding to an observed significance of 4.5 σ (3.9 σ expected). The result is consistent with the Standard Model prediction.
