Measurement of d sigma/dy for high mass Drell-Yan e(+)e(-) pairs from p(p)over-bar collisions at root s=1.8 TeV

We report on the first measurement of the rapidity distribution d sigma /dy over nearly the entire kinematic region of rapidity for e(+)e(-) pairs in both the Z-boson region of 66<M-ee< 116 GeV/c(2) and in the high mass region of M-ee> 116 GeV/c(2). The data sample consists of 108 pb(-1) of p<(p)over bar> collisions at roots = 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 ph. The measured total cross section and d sigma /dy are compared with quantum chromodynamics calculations in leading and higher orders.
