TL;DR

This paper reports a measurement of the Z boson differential cross section as a function of transverse momentum in proton-antiproton collisions at 1.8 TeV, comparing results with theoretical predictions and extracting non-perturbative parameters.

Contribution

The study provides the first detailed measurement of Z boson transverse momentum distribution at Tevatron energies and tests NNLO resummation predictions against experimental data.

Findings

Good agreement with NNLO resummation predictions

Extraction of non-perturbative parameters from data

Validation of theoretical models for Z boson production

Abstract

We present a measurement of the differential cross section as a function of transverse momentum of the Z boson in ppbar collisions at sqrt{s}=1.8 TeV using data collected by the D0 experiment at the Fermilab Tevatron Collider during 1994--1996. We find good agreement between our data and the NNLO resummation prediction and extract values of the non-perturbative parameters for the resummed prediction from a fit to the differential cross section.
