Measurement and qcd analysis of inclusive jet production in deep inelastic scattering at hera

A new measurement of inclusive jet cross sections in deep inelastic scattering using the ZEUS detector at the HERA collider is obtained. The data were taken at HERA 2 at a center-of-mass energy of 318 GeV and correspond to an integrated luminosity of 347 pb(-1). The measured jet cross sections are compared to previous measurements as well as NNLO QCD theory predictions. The measurement is used in a QCD analysis at NNLO accuracy to perform a simultaneous determination of parton distribution functions of the proton and the strong coupling constant, resulting in a value of alpha(s)(M-Z(2)) = 0.1138 +/- 0.0014 (exp/fit) (+0.0004)(-0.0008) (model/param.) (+0.0008)(-0.0007) (scale). A significantly improved accuracy is observed compared to similar measurements of the strong coupling constant.
