Wt. Giele et S. Keller, IMPLICATIONS OF HADRON COLLIDER OBSERVABLES ON PARTON DISTRIBUTION FUNCTION UNCERTAINTIES - ART. NO. 094023, Physical review. D. Particles and fields, 5809(9), 1998, pp. 4023
Standard parton distribution function sets do not have rigorously quan
tified uncertainties. In recent years it has become apparent that thes
e uncertainties play an important role in the interpretation of hadron
collider data. In this paper, using the framework of statistical infe
rence, we illustrate a technique that can be used to efficiently propa
gate the uncertainties to new observables, assess the compatibility of
new data with an initial fit, and, in case the compatibility is good,
include the new data in the fit. [S0556-2821(98)02019-0]
