Abstract
The HERAPDF2.0 family, introduced in 2015, is completed
with fits HERAPDF2.0Jets NNLO (prel.) based on inclusive
HERA data and selected jet production data.
The result of a fit with the strong coupling constant, $a_s(M^2_z)$, free is
$a_s(M^2_z)$ $= 0.1150 \pm 0.0008{\rm (exp)} ^{+0.0002}_{-0.0005}$
(model/parameterisation) $\pm 0.0006{\rm (hadronisation)} \pm 0.0027 {\rm (scale)}$.
Sets of parton density functions, PDFs, from fits with fixed
$a_s(M^2_z)$ $= 0.115$ and $a_s(M^2_z)$ $= 0.118$ are presented and compared.
