CTEQ-TEA parton distribution functions with intrinsic charm
Marco Guzzi, Tie-Jiun Hou, Sayipjamal Dulat +7
The possibility of a (sizable) nonperturbative contribution to the charm parton distribution function (PDF) in a nucleon is investigated together with theoretical issues arising in…
A New Method for Reducing PDF Uncertainties in the High-Mass Drell-Yan Spectrum
Christopher Willis, Raymond Brock, Daniel Hayden +4
Uncertainties in the parametrization of Parton Distribution Functions (PDFs) are becoming a serious limiting systematic uncertainty in Large Hadron Collider (LHC) searches for Beyo…
Updating and Optimizing Error PDFs in the Hessian Approach
Carl Schmidt, Jon Pumplin, C. -P. Yuan
We discuss how to apply the Hessian method (i) to predict the impact of a new data set (or sets) on the parton distribution functions (PDFs) and their errors, by producing an updat…
