W/Z/Higgs Production at LHC and PDF Uncertainties

At the LHC, W and Z boson production will be used as ``benchmark'' processes to calibrate various searches for the Higgs boson, SUSY, and other ``new physics'' processes. In the context of the PDF global analysis, we examine current data from HERA, Tevatron, and fixed-targets to properly quantify the PDF uncertainties. This helps us distinguish ``new physics'' from ``old physics,'' and thereby maximize the discovery potential of the LHC.
