Theoretical, parametrization, and sampling uncertainties in parton distributions: a view from CT
Low x, PDFs and hadronic final states
I summarize recent studies of various types of uncertainties in the global analysis of parton distribution functions (PDFs) by the CTEQ-TEA group. Sampling of the multivariate PDF parameter space introduces an important source of uncertainty that has implications for critical collider applications such as W boson mass measurement and Higgs physics. Parametrization and sampling uncertainties...
