The study of uncertainties in theory predictions in single inclusive jet production cross section using the APPLGRID package
Abstract
A method to facilitate the consistent inclusion of cross-section measurements in proton parton density functions (PDFs) fits in NLO QCD has been developed. It allows the a posteriori variation of the renormalisation and factorisation scales and of the centre-of-mass energy and the inclusion of arbitrary PDFs, strong coupling in cross-section calculations. The theoretical uncertainties in the double differential single inclusive jet cross-section at a s=7 TeV have been studied using this method.
