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

Abstract

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 66 116 GeV/c(2). The data sample consists of 108 pb(-1) of p 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
