Limits on quark compositeness from high-energy jets in pp collisions at 1.8 TeV

Limits on quark compositeness from high-energy jets in pp collisions at 1.8 TeV
Events in ¯pp collisions at √s=1.8TeV with total transverse energy exceeding 500GeV are used to set limits on quark substructure. The data are consistent with next-to-leading order QCD calculations. We set a lower limit of 2.0TeV at 95% confidence on the energy scale ΛLL for compositeness in quarks, assuming a model with a left-left isoscalar contact interaction term. The limits on ΛLL are found to be insensitive to the sign of the interference term in the Lagrangian.

Abstract

Events in ¯pp collisions at √s=1.8TeV with total transverse energy exceeding 500GeV are used to set limits on quark substructure. The data are consistent with next-to-leading order QCD calculations. We set a lower limit of 2.0TeV at 95% confidence on the energy scale ΛLL for compositeness in quarks, assuming a model with a left-left isoscalar contact interaction term. The limits on ΛLL are found to be insensitive to the sign of the interference term in the Lagrangian.
