  "abstract": "The inclusive cross-section for the associated production of a $W$ boson and top quark is measured using data from proton-proton collisions at $\\sqrt{s}={13}\\text{TeV}$. The dataset corresponds to an integrated luminosity of 3.2 fb$^{-1}$, and was collected in 2015 by the ATLAS detector at the Large Hadron Collider at CERN. Events are selected requiring two opposite sign isolated leptons and at least one jet; they are separated into signal and control regions based on their jet multiplicity and the number of jets that are identified as containing $b$ hadrons. The $Wt$ signal is then separated from the $t\\bar{t}$ background using boosted decision tree discriminants in two regions. The cross-section is extracted by fitting templates to the data distributions, and is measured to be $94 \\pm 10$ (stat.)$^{+28}_{-22}$ (syst.) $\\pm 2$ (lumi.) pb. The measurement is in agreement with the Standard Model prediction.",
