| We report on a measurement of the rapidity distribution, dsigma/ dy, for Z/Drell-Yan → ee events produced in pp collisions at s = 1.96 TeV. The data sample consists of 2.13 fb-1 corresponding to about about 160,000 Z/Drell-Yan → ee candidates in the Z boson mass region collected by the Collider Detector at Fermilab. The dsigma/dy distribution, which is measured over the full kinematic range for e +e-- pairs in the invariant mass range 66 < Mee < 116 GeV/c 2, is compared with theory predictions. There is good agreement between the data and predictions of Quantum Chromodynamics in Next to Leading Order with the CTEQ6.1M Parton Distribution Functions. |
