Measurement of inclusive differential cross sections for Upsilon(1S) production in p-pbar collisions at sqrt(s) = 1.96 TeV

TL;DR

This paper reports measurements of the inclusive differential cross sections for Upsilon(1S) production in proton-antiproton collisions at 1.96 TeV, using muon decay channels to analyze data from the D0 detector at Fermilab.

Contribution

It provides the first detailed differential cross section measurements of Upsilon(1S) production at Tevatron energies across different rapidity ranges.

Findings

Measured differential cross sections as a function of transverse momentum.

Analyzed three rapidity ranges: 0-0.6, 0.6-1.2, 1.2-1.8.

Results help constrain bottomonium production models.

Abstract

We present measurements of the inclusive production cross sections of the Upsilon(1S) bottomonium state in ppbar collisions at sqrt(s) = 1.96 TeV. Using the Upsilon(1S) to mu+mu- decay mode for a data sample of 159 +- 10 pb^-1 collected by the D0 detector at the Fermilab Tevatron collider, we determine the differential cross sections as a function of the Upsilon(1S) transverse momentum for three ranges of the Upsilon(1S) rapidity: 0 < |y| < 0.6, 0.6 < |y| < 1.2, and 1.2 < |y| < 1.8.
