“…The first observation of jet production in DIS was made by the fixed-target E665 experiment [50]. Shortly thereafter, the experiments H1 and ZEUS at the electron-proton collider HERA embarked on a large program of jet production studies in deep inelastic scattering, with measurements both in the laboratory frame [51][52][53][54] and in the Breit frame [55,56].…”

Computations of higher-order QCD corrections for processes with exclusive final states require a subtraction method for real-radiation contributions. We present the first-ever generalisation of a subtraction method for third-order (N 3 LO) QCD corrections. The Projection-to-Born method is used to combine inclusive N 3 LO coefficient functions with an exclusive second-order (NNLO) calculation for a final state with an extra jet. The input requirements, advantages, and potential applications of the method are discussed, and validations at lower orders are performed. As a test case, we compute the N 3 LO corrections to kinematical distributions and production rates for single-jet production in deep inelastic scattering in the laboratory frame, and compare them with data from the ZEUS experiment at HERA. The corrections are small in the central rapidity region, where they stabilize the predictions to sub per-cent level. The corrections increase substantially towards forward rapidity where large logarithmic effects are expected, thereby yielding an improved description of the data in this region.

“…Jet production in DIS has been measured [49] in the laboratory frame [50][51][52][53][54] and in the Breit frame [55,56]. In the latter, the virtual photon and the proton collide head-on and the basic lepton-quark scattering process always yields a quark at zero transverse momentum.…”

Renormalisation scale uncertainty in the DIS 2+1 jet cross-section

The Deep Inelastic Scattering 2+1 jet cross-section is a useful observable for precision tests of QCD, e.g. measuring the strong coupling constant s . A consistent analysis requires a good understanding of the theoretical uncertainties and one of the fundamental ones in QCD is due to the renormalisation scheme and scale ambiguity. Di erent methods, which have been proposed to resolve the scale ambiguity, are applied to the 2+1 jet crosssection and the uncertainty is estimated. It is shown that the uncertainty can be made smaller by choosing the jet de nition in a suitable way.
