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

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 p 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 alpha s(MZ) at NLO; alphas = 0.11830.0028(exp.)0.0008(model). An additional uncertainty from the choice of scales is estimated as 0.005. This is the first extraction of alphas(MZ) from HERA data alone. Springer-Verlag/Societ Italiana de Fisica 2005.
