The transverse momentum and total cross section of e+e− pairs in the Z-boson region of 66<Mee<116GeV/c2 from pp¯ collisions at √s=1.8TeV 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.
