An NLO QCD analysis of inclusive cross-section and jet-production data from the ZEUS experiment

Abstract:: The ZEUS inclusive differential cross-section data from HERA, for charged and neutral current processes taken with e+ and e− beams, together with differential cross-section data on inclusive jet production in e+p scattering and dijet production in γp scattering, have been used in a new NLO QCD analysis to extract the parton distribution functions of the proton. The input of jet-production data constrains the gluon and allows an accurate extraction of αs (MZ) at NLO;

αs (MZ) = 0.1183 ± 0.0028(exp.) ± 0.0008(model).

An additional uncertainty from the choice of scales is estimated as ±0.005. This is the first extraction of αs (MZ) from HERA data alone.
