Global QCD Analysis, the Gluon Distribution, and High Et Inclusive Jet Data'

摘要

We report on an extensive global QCD analysis of new DIS and hadronic inclusive jet production data emphasizing the impact of these recent data on the deter-mination of the gluon distribution, and on the interpretation of the high Et jets highlighted by the CDF collaboration. This analysis results in (i) a better han-dle on the range of uncertainty of the gluon distribution, (ii) a new generation of CTEQ parton distributions which incorporates this uncertainty, (iii) a viable sce-nario for accommodating the high Et jets in the conventional pQCD framework, and (iv) a systematic study of the sensitivity of the various hard processes to as and the consistency of as determination in global analysis.
