Limits on quark-lepton compositeness scales from dileptons produced in 1.8 TeV p(p)over-bar collisions

Abstract:

The dilepton mass spectrum in pp̄ → 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 g0 2/4π = 1, limits on chiral quark-electron and quark-muon...
