Transverse Momentum and Total Cross Section of ${\mathit{e}}^{+}{\mathit{e}}^{-}$ Pairs in the Z-Boson Region from $\mathit{p}\overline{\mathit{p}}$ Collisions at $\sqrt{\mathit{s}}=1.8\mathrm{}\mathrm{TeV}$

The transverse momentum and total cross section of $e^{+}{e}^{-}$ pairs in the $Z$-boson region of $66<\mathrm{}{M}_{\mathrm{ee}}<116\mathrm{GeV}{/c}^2$ from $p\overline{p}$ collisions at $\sqrt{s}=1.8\mathrm{TeV}$ are measured using $110{\mathrm{pb}}^{-1\mathrm{}}$ of collisions taken by the Collider Detector at Fermilab during 1992–1995. The total cross section is measured to be $248\pm 11\mathrm{pb}$. 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.
