Jet production in charged-current deep-inelastic scattering to third order in QCD

Gehrmann, T; Huss, A; Niehues, J; Vogt, A; Walker, D M (2019). Jet production in charged-current deep-inelastic scattering to third order in QCD. Physics Letters B, 792:182-186.

Abstract

The production of jets in charged-current deep-inelastic scattering (CC DIS) probes simultaneously the strong and the electroweak sectors of the Standard Model; its measurement provides important information on the quark flavour structure of the proton. We compute third-order (LO ) perturbative QCD corrections to this process, fully differential in the jet and lepton kinematics. We observe a substantial reduction in the theory uncertainty, to sub-percent level throughout the relevant kinematical range, thus enabling precision phenomenology with jet observables.
