Dijet production from {bar p}p collisions at 1.8 TeV

PDF Version Also Available for Download.

Description

The production properties of dijets from {ital p{anti p}} collisions at {radical}{ital s} = 1.8 TeV have been studied using the Collider Detector at Fermilab. This report presents an analysis of the dijet angular distributions using 106 pb{sup -1} of data collected during Run I of the Tevatron Collider. The measured angular distributions agree with next-to-leading order QCD predictions in five dijet invariant mass regions with average dijet mass varying from 263 to 698 GeV/c{sup 2}. The predicted angular distributions are relatively insensitive to parton distribution functions, and therefore these data can be used to put limits on energy scale ... continued below

Description

The production properties of dijets from {ital p{anti p}} collisions at {radical}{ital s} = 1.8 TeV have been studied using the Collider Detector at Fermilab. This report presents an analysis of the dijet angular distributions using 106 pb{sup -1} of data collected during Run I of the Tevatron Collider. The measured angular distributions agree with next-to-leading order QCD predictions in five dijet invariant mass regions with average dijet mass varying from 263 to 698 GeV/c{sup 2}. The predicted angular distributions are relatively insensitive to parton distribution functions, and therefore these data can be used to put limits on energy scale parameters used to describe contact interactions. For a model with only up and down quarks composite, the data exclude at 95% confidence level a contact interaction scale {Lambda}{sub {ital ud}}{sup +} {<=} 1.6 TeV of {Lambda}{sub {ital ud}}{sup -} {<=} 1.4 TeV.
