Impact of jet-production data on the next-to-next-to-leading-order determination of HERAPDF2.0 parton distributions
Original language description
The HERAPDF2.0 ensemble of parton distribution functions (PDFs) was introduced in 2015. The final stage is presented, 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 the H1 and ZEUS collaborations. A perturbative QCD fit, simultaneously of αs(MZ2)αs(MZ2) and the PDFs, was performed with the result αs(MZ2)=0.1156±0.0011 (exp) −0.0002+0.0001 (model+parameterisation) ±0.0029 (scale)αs(MZ2)=0.1156±0.0011 (exp) −0.0002+0.0001 (model+parameterisation) ±0.0029 (scale). The PDF sets of HERAPDF2.0Jets NNLO were determined with separate fits using two fixed values of αs(MZ2)αs(MZ2), αs(MZ2)=0.1155αs(MZ2)=0.1155 and 0.118, since the latter value was already chosen for the published HERAPDF2.0 NNLO analysis based on HERA inclusive DIS data only.
