Limits on Quark-Lepton Compositeness Scales from Dileptons Produced in 1.8 TeV Collisions
F Abe, H Akimoto, A Akopian, MG Albrow… - Physical review …, 1997 - APS
The dilepton mass spectrum in pp→ l+ l−+ X interactions is studied using dielectrons (ee)
and dimuons (μμ) in 110 pb− 1 of data collected with the Collider Detector at Fermilab. The
data are consistent with standard model predictions. The mass spectrum, being a probe for
new physics, is examined for new interactions of quarks and leptons from a common
composite structure. Assuming a contact interaction with the conventional coupling g 0 2/4
