We report on a CDF measurement of the total cross section and rapidity distribution, dσ/dy, for γ*Z→e+e- events in the Z boson mass region (66<116 GeV/c2) produced in pp- collisions at s=1.96 TeV with 2.1 fb-1 of integrated luminosity. The measured cross section of 257±16 pb and dσ/dy distribution are compared with Next-to-Leading-Order (NLO) and Next-to-Next-to-Leading-Order (NNLO) QCD theory predictions with CTEQ and MRST/MSTW parton distribution functions (PDFs). There is good agreement between the experimental total cross section and dσ/dy measurements with theoretical calculations with the most recent NNLO PDFs. © 2010 Elsevier B.V.

Abstract

We report on a CDF measurement of the total cross section and rapidity distribution, dσ/dy, for γ*Z→e+e- events in the Z boson mass region (66<116 GeV/c2) produced in pp- collisions at s=1.96 TeV with 2.1 fb-1 of integrated luminosity. The measured cross section of 257±16 pb and dσ/dy distribution are compared with Next-to-Leading-Order (NLO) and Next-to-Next-to-Leading-Order (NNLO) QCD theory predictions with CTEQ and MRST/MSTW parton distribution functions (PDFs). There is good agreement between the experimental total cross section and dσ/dy measurements with theoretical calculations with the most recent NNLO PDFs. © 2010 Elsevier B.V.
