Abstract:

Inclusive jet differential cross sections have been measured in neutral current deep inelastic e ⁺p scattering for boson virtualities Q ² > 125 GeV ². 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 are presented as functions of jet transverse energy (E ^B T.jet), jet pseudorapidity and Q ², for jets with E ^B T.jet > 8 GeV. Next-to-leading-order QCD calculations agree well with the measurements both at high Q ² and high E ^B T.jet. The value of α s(M z), determined from an analysis of dσ/dQ ² for Q ² > 500 GeV ², is α s(M Z=0.1212±0.0017 (stat.) ^+0.0023 -0.0031 (syst.) ^+0.0028 -0.0027(th.). © 2002 Elsevier Science B.V.
