Transverse momentum and total cross section of e+e- pairs in the Z-boson region from p(p)over-bar collisions at √s=1.8 TeV

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.
