Abstract
We report on the first measurement of the rapidity distribution dsigma/dy over nearly the entire kinematic region of rapidity for e+e- pairs in the Z-boson region of 66<M_ee<116 GeV/c2 and at higher mass M_ee>116 GeV/c2. The data sample consists of 108 pb-1 of pbar-p collisions at sqrt{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 measured total cross section and dsigma/dy are compared with quantum chromodynamics calculations in leading and higher orders.
