We report on the first measurement of the rapidity distribution ds/dy over nearly the entire kinematic region of rapidity for e+ e- pairs in both the Z-boson region of 66<Mee<116 GeV/c2 and in the high mass region of 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 measured total cross section and ds/dy are compared with quantum chromodynamics calculations in leading and higher orders.

Abstract

We report on the first measurement of the rapidity distribution ds/dy over nearly the entire kinematic region of rapidity for e+ e- pairs in both the Z-boson region of 66116 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 measured total cross section and ds/dy are compared with quantum chromodynamics calculations in leading and higher orders.
