Differential Production Cross Section ofZBosons as a Function of Transverse Momentum ats=1.8TeVTeV

We present a measurement of the transverse momentum distribution of $Z$ bosons produced in $p\overline{p}$ collisions at $\sqrt{s}=1.8\mathrm{}$ TeV from data collected by the DØ experiment at the Fermilab Tevatron Collider. We find good agreement between our results and current resummation calculations, and also use our data to extract nonperturbative parameters for a particular version of the resummation formalism. The resulting values are significantly more precise than obtained in previous determinations.
