Resumo(s)
The differential cross-section for the production of a W boson in association with a top quark is measured for several particle-level observables. The measurements are performed using ${36.1}\,\text {fb}^{-1}$ of pp collision data collected with the ATLAS detector at the LHC in 2015 and 2016. Differential cross-sections are measured in a fiducial phase space defined by the presence of two charged leptons and exactly one jet matched to a b-hadron, and are normalised with the fiducial cross-section. Results are found to be in good agreement with predictions from several Monte Carlo event generators.
