HERAPDF2.0Jets NNLO (prel.), the completion of the HERAPDF2.0 family

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, ${\alpha }_s(M_Z^2)$, free is ${\alpha }_s(M_Z^2)=0.1150\pm 0.0008{(\exp )}_{-0.0005}^{+0.0002}$ (model/parameterisation) $\pm 0.0006(\mathrm{hadronisation})\pm 0.0027(\mathrm{scale})$. Sets of parton density functions, PDFs, from fits with fixed ${\alpha }_s(M_Z^2)=0.115$ and ${\alpha }_s(M_Z^2)=0.118$ are presented and compared.
