| We report on the first measurement of the rapidity distribution, dsigma/dy, over the full kinematic range for e+e- pairs in the Z boson region of 66 < Mee < 116 GeV/c2. The data sample consists of 108 pb-1 of pp¯ collisions at s = 1.8 TeV taken by the Collider Detector at Fermilab during 1992--1995. The total cross section in the Z-boson region is measured to be 252 +/- 11 pb. The total cross section and dsigma/ dy are compared with Quantum Chromodynamics calculations in leading order, next-to-leading-order (NLO), next-to-next-leading-order, and NLO with gluon resummation. |
