TL;DR
This paper reports the first measurement of J/Psi production cross section in the forward region in proton-antiproton collisions at 1.8 TeV, providing data to test charmonium production models.
Contribution
It provides the first measurement of inclusive J/Psi production cross section in the forward pseudorapidity region at Tevatron energies.
Findings
Measured cross section for 1 < pT < 16 GeV/c
Data compared with theoretical charmonium production models
Results constrain models of J/Psi production
Abstract
This paper presents the first measurement of the inclusive J/Psi production cross section in the forward pseudorapidity region 2.5<|eta|<3.7 in ppbar collisions at sqrt(s)=1.8TeV. The results are based on 9.8 pb-1 of data collected using the D0 detector at the Fermilab Tevatron Collider. The inclusive J/Psi cross section for transverse momenta between 1 and 16 GeV/c is compared with theoretical models of charmonium production.
