Differential Production Cross Section of Z Bosons as a Function of Transverse Momentum at sqrt{s}=1.8 TeV

TL;DR

This paper measures the Z boson transverse momentum distribution at 1.8 TeV, compares it with theoretical resummation calculations, and refines the non-perturbative parameters with higher precision.

Contribution

It provides the first detailed measurement of Z boson transverse momentum distribution at Tevatron energies and improves the precision of non-perturbative parameter extraction.

Findings

Good agreement with resummation calculations

More precise non-perturbative parameter values obtained

Enhanced understanding of Z boson production dynamics

Abstract

We present a measurement of the transverse momentum distribution of Z bosons produced 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 a current resummation calculation. We also use our data to extract values of the non-perturbative parameters for a particular version of the resummation formalism, obtaining significantly more precise values than previous determinations.
