Jet cross sections in neutral current deep inelastic scattering at ZEUS and determination of alphas

The latest results on jet cross sections in neutral current deep inelastic $ep$ scattering from the ZEUS Collaboration are presented. The new results were used to perform stringent tests of perturbative QCD and extract precise values of the strong coupling. Also, the measurements have the potential to constrain further the parton distribution functions in the proton if included in QCD fits.
