National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

PDF Uncertainties in W H Production at Tevatron.

DE141131181

Publication Date	2001
Personal Author	Nadolsky, P. M.; Sullivan, Z.
Page Count	3
Abstract	We apply a method proposed by members of CTEQ Collaboration to estimate the uncertainty in associated W-Higgs boson production at Run II of the Tevatron due to our imprecise knowledge of parton distribution functions. We find that the PDF uncertainties for the signal and background rates are of the order 3%. The PDF uncertainties for the important statistical quantities (significance of the Higgs boson discovery, accuracy of the measurement of the WH cross section) are smaller (1.5%) due to the strong correlation of the signal and background.
