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 $p\bar{p}$ collisions at $\sqrt{s}=1.8$ 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 $248 \pm 11$ 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.

The measured transverse momentum distribution of e+e- pairs in the Z0 bosonregion. PT is the centre of the bins.

The total cross section for e+e- pair production in the Z0 region. The mainerror is the statistical and efficiency error, the first DSYS error is the syst ematic error from the background subtractions and the second DSYS error is from the collision luminosity.
