The transverse momentum and total cross section of e(+)e(-) pairs in the Z-boson region of 66 < M-ee < 116 GeV/c(2) from p (p) over bar collisions at root s = 1.8 TeV are measured using 110 pb(-1) of collisions taken by the Collider Detector at Fermilab during 1992-1995. The total cross section is measured to be 248 +/- 11 pb. The differential transverse momentum cross section is compared with calculations that match quantum chromodynamics perturbation theory at high transverse momentum with the gluon resummation formalism at low transverse momentum.

Abstract
The transverse momentum and total cross section of e(+)e(-) pairs in the Z-boson region of 66 < M-ee < 116 GeV/c(2) from p (p) over bar collisions at root s = 1.8 TeV are measured using 110 pb(-1) of collisions taken by the Collider Detector at Fermilab during 1992-1995. The total cross section is measured to be 248 +/- 11 pb. The differential transverse momentum cross section is compared with calculations that match quantum chromodynamics perturbation theory at high transverse momentum with the gluon resummation formalism at low transverse momentum.
