Measurement of differential cross sections in the process pp→ W⁺W⁻bb — Stefan Kluth, Daniel Britzger, and •Johannes Hessler — Max-Planck-Institut für Physik

Precise measurements of differential cross sections in the process pp→ W⁺W⁻bb offer an outstandingly rich physics potential at highest precision. Although the process is theoretically and experimentally well defined, dedicated measurements of W⁺W⁻bb production cross sections were not (extensively) performed in the past at the LHC. We will report on ongoing measurements in the single-lepton channel with Run-II data taken by the ATLAS experiment. Due to the high jet multiplicity of the final state the event reconstruction can be challenging. This talk will focus on the kinematic reconstruction of the hadronically decaying W-boson.
