Parton distributions and the LHC: W and Z production

“…The missing interval, 0 < x < 10 −5 , accounts for the small departure of the MRST99 total from 1. partons are used. Experimental measurements from UA1 [11], UA2 [12], CDF [13] and D0 [14] are also shown. Table 1) with an enhanced d/u ratio at large x.…”

“…Note that an important component of the experimental error is due to the luminosity measurement and uncertainty. The latter is quoted as ±3.6% for CDF and ±5.4% for D0[13,14]. In addition, the value assumed for the total pp cross section is slightly different for the two experiments, and this may account in part for the systematically smaller D0 cross sections displayed inFig.…”

“…The error bars on the default MRST prediction correspond to a scale variation of µ = M V /2 → 2M V , V = W, Z. Experimental measurements from CDF[13] and D0[14] are shown.…”

“…' Until recently, most measurements of W and Z/γ * production in hadronic interactions have been confined to experiments using proton-antiproton collisions. First results were obtained by the UA1 [1,2] and UA2 [3,4] collaborations at √ s = 630 GeV at the CERN SppS facility, followed by the CDF [5,6] and D0 [7,8] pp measurements at the Fermilab Tevatron, at √ s = 1.8 and 1.96 TeV. It is only in the last few years that pp colliders have reached sufficient center of mass energies for comparable studies, at √ s = 500 GeV by the STAR (Solenoidal Tracker at RHIC) [9] and PHENIX [10] collaborations at the Relativistic Heavy Ion Collider (RHIC), and most recently by the LHC experiments ATLAS [11] and CMS [12,13] at √ s = 7 TeV.…”

Electroweak radiative corrections to W and Z boson production in hadronic collisions

“…This procedure completely eliminates the mass singular logarithms and, therefore, strongly reduces the size of the O(α) corrections. In contrast, photons which are almost collinear with muons are rejected if they are too energetic [15,25] which results in residual mass singular logarithmic corrections to observable quantities in W production. Finally, our conclusions are presented in Sec.…”
