| 英文摘要 | The inclusive cross-section for the associated production of a w boson and top quark is measured using data from proton-proton collisions at root s = 13tev. 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 ($) over bar 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 sigma(wt) = 94 +/- 10 (stat:)(-22)(+28) (syst:) +/- 2 (lumi:) pb. the measured value is in good agreement with the sm prediction of sigma(theory) = 71: 7 +/- 1: 8 (scale) +/- 3: 4 (pdf) pb [1]. |
