Measurement of $dσ/dy$ of Drell-Yan $e^+e^-$ pairs in the $Z$ Mass Region from $p\bar{p}$ Collisions at $\sqrt{s}=1.96$ TeV

Abstract

We report on a CDF measurement of the total cross section and rapidity distribution,

, for

events in the

boson mass region (

GeV/c

) produced in

collisions at

TeV with 2.1fb

of integrated luminosity. The measured cross section of

pb and

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

measurements with theoretical calculations with the most recent NNLO PDFs.
