Multiple Jet Production at Low Transverse Energies in pbarp Collisions at sqrt(s) = 1.8 TeV

TL;DR

This paper reports measurements of multiple jet production in proton-antiproton collisions at 1.8 TeV, highlighting discrepancies between experimental data and theoretical QCD calculations, especially in angular and transverse momentum distributions.

Contribution

It provides new experimental data on multi-jet production at high energies and compares it with existing QCD models, revealing significant discrepancies.

Findings

Discrepancies between data and PYTHIA/JETRAD predictions for three and four-jet events.

Notable differences in angular distributions of multiple jets.

Transverse momentum distributions also show disagreement with models.

Abstract

We present data on multiple jet production for transverse energies greater than 20 GeV in pbarp collisions at sqrt(s) = 1.8 TeV. QCD calculations in the parton shower approximation (PYTHIA) and in the next-to-leading order approximation (JETRAD) show discrepancies with data for three and four-jet production. This disagreement is especially apparent in multiple jet angular and transverse momentum distributions.
