B. Abbott et al., Differential production cross section of Z bosons as a function of transverse momentum at root s=1.8 TeV, PHYS REV L, 84(13), 2000, pp. 2792-2797
We present a measurement of the transverse momentum distribution of Z boson
s produced in p (p) over bar collisions at root s = 1.8 TeV from data colle
cted by the DO experiment at the Fermilab Tevatron Collider, We find good a
greement between our results and current resummation calculations, and also
use our data to extract nonperturbative parameters for a particular versio
n of the resummation formalism. The resulting values are significantly more
precise than obtained in previous determinations.
