abstract = {The HERAPDF2.0 ensemble of parton distribution functions
(PDFs) was introduced in 2015. Presented is the final stage,
a next-to-next-to-leading order (NNLO) analysis of the HERA
data on inclusive deep inelastic ep scattering together with
jet data as published by H1 and ZEUS. A pQCD fit to the data
with free $\alpha_s(M_Z^2)$ and free PDFs was used to
determine $\alpha_s(M_Z^2)$ with the result
$\alpha_s(M_Z^2)$ = 0.1156±0.0011 (exp)
$^{+0.0001}_{-0.0002}$ (model + parameterisation) ±0.0029
(scale). The PDF sets of HERAPDF2.0Jets NNLO were determined
with fits using fixed the fixed values of $\alpha_s(M_Z^2)$
= 0.1155 and $\alpha_s(M_Z^2)$ = 0.118. The latter value was
already chosen for the published HERAPDF2.0 NNLO analysis
based on inclusive data only. The different sets of PDFs are
presented and compared. The similarity of the PDFs
demonstrates the consistency of inclusive and jet-production
cross-section data. Predictions based on HERAPDF2.0Jets NNLO
agree very well with the jet-production data used in the
fits.},
