Sensitivity to quark and lepton compositeness at the Tevatron
- Rochester U.
- Fermilab
We present a study of the sensitivity of CDF to quark and lepton compositeness assuming 2 fb{sup -1} (Run II) and 30 fb{sup -1} (TeV33) of integrated luminosity for future Tevatron collider runs. We calculate the expected number of Drell-Yan dielectron events in the standard model, and compare it to the predicted number of events from a {ital q{anti q}} {r_arrow} {ital e{anti e}} left-handed contact interaction, as a function of dielectron invariant mass, for various values of the compositeness scale, {Lambda}. Preliminary CDF limits on a {ital q{anti q}} {r_arrow} {ital l{anti l}} contact interaction scale using 110 pb{sup -1} of Run I data are between 3 and 4 TeV, depending on the channel and theoretical model. With 2 fb{sup -1} of integrated luminosity in Run II, the Tevatron will be sensitive to a compositeness scale of {Lambda}{sup +} {<=} 6.5 TeV and {Lambda}{sup -} {<=} 10 TeV. Assuming present detector performance, with 30 fb{sup -1} of integrated luminosity from TeV33, the Tevatron will be sensitive to a compositeness scale of {Lambda}{sup +} {<=} 14 TeV and {Lambda}{sup -} {<=} 20 TeV, in the {ital ee} channel.
