Differential production cross section of Z bosons as a function of transverse momentum at root s=1.8 TeV

We present a measurement of the transverse momentum distribution of Z bosons produced in pp collisions at √s = 1.8 TeV from data collected by the D 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. © 2000 The American Physical Society
