Determination of PDFs at the LHC

At ATLAS, sensitivity to many new physics channels is reduced by uncertainty in the high-x gluon PDF. In order to improve this PDF a grid based on [1] has been developed for including ATLAS jet data (in regions where new physics is not expected) into PDF fits. This method has been used to evaluate t...

Sumario:At ATLAS, sensitivity to many new physics channels is reduced by uncertainty in the high-x gluon PDF. In order to improve this PDF a grid based on [1] has been developed for including ATLAS jet data (in regions where new physics is not expected) into PDF fits. This method has been used to evaluate the impact of inclusive jet-cross-section data at ATLAS on constraining the high x-gluon.
