HERAPDF2.0Jets NNLO (prel.), the completion of the HERAPDF2.0 family (1906.01884v2)

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