Abstract
The production of jets is studied in deep-inelastic e ± p scattering at large negative four momentum transfer squared 150<Q 2<15000 GeV2 using HERA data taken in 19992007, corresponding to an integrated luminosity of 395 pb−1. Inclusive jet, 2-jet and 3-jet cross sections, normalised to the neutral current deep-inelastic scattering cross sections, are measured as functions of Q 2, jet transverse momentum and proton momentum fraction. The measurements are well described by perturbative QCD calculations at next-to-leading order corrected for hadronisation effects. The strong coupling as determined from these measurements is $\alpha_{s}(M_{Z})=0.1168\pm0.0007\,\mathrm{(exp.)}{}
