Abstract: 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 $\alpha _{\mathrm {s}}(M_{Z}^2)$ = 0.1138 $\pm$ 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.
