Abstract

Inclusive jet differential cross sections have been measured in neutral current deep inelastic e(+)p scattering for boson virtualities Q(2) gt 125 GeV2. The data were taken using the ZEUS detector at HERA and correspond to an integrated luminosity of 38.6 pb(-1). Jets were identified in the Breit frame using the longitudinally invariant k(T) cluster algorithm. Measurements of differential inclusive jet cross sections a-re presented as functions of jet transverse energy (E-T.jet(B)), jet pseudorapidity and Q(2), for jets with E- T.jet(B) gt 8 GeV. Next-to-leading-order QCD calculations agree well with the measurements both at high Q(2) and high E- T.jet(B). The value of alpha(s) (M-Z), determined from an analysis of dsigma/dQ(2) for Q(2) gt GeV2, is alphas (M-Z) = 0.1212 +/- 0.0017(stat.)(-0.0031)(+0.0023)(syst.)(- 0.0027)(+0.0028)(th.).
