abstract = {The measurement of jet production in $e^\pm p$ scattering
at HERA is an important input for the understanding of QCD
and a well established tool to test perturbative QCD
predictions. Jet cross sections can be used to precisely
determine the strong coupling constant and its correlation
to the gluon distribution function of the proton. A new
measurement of inclusive jet cross sections in neutral
current 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 $318\,\text{GeV}$ and
correspond to an integrated luminosity of $347{pb}^{-1}$.
Massless jets, reconstructed using the $k_\perp$-algorithm
in the Breit reference frame, are measured as a function of
the squared momentum transfer $Q^2$ and the transverse
momentum of the jets in the Breit frame
$p_{\perp,\text{Breit}}$. 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
$alpha_\text{s}(M_\text{Z}^2) = 0.1138 \pm 0.0014 \text{
(exp/fit) } {}^{+0.0004}_{-0.0008} \text{ (model/param.) }
{}^{+0.0008}_{-0.0007} \text{ (scale)}$. A significantly
improved accuracy is observed compared to similar
measurements of the strong coupling constant.},
