QCD Analysis with determination of ${\alpha }_S(M_Z)$ based on HERA inclusive and jet data

Abstract

HERA jet data, in addition to combined HERA inclusive data, are input to the HERAPDF NLO QCD analysis in order to further constrain the gluon PDF and to allow an accurate evaluation of ${\alpha }_S(M_Z)$
