The Transverse Momentum and Total Cross Section of E+ E- Pairs in the Z-Boson Region from P Anti-P Collisions at s**(1/2) = 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 from collisions at
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 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.Comment: Accepted for Publication in Phys. Rev. Letters, 7 page
