Top-quark{endash}charm-quark strong flavor-changing neutral currents at the Fermilab Tevatron
- Department of Physics and Astronomy, Michigan State University, East Lansing, Michigan 48824 (United States)
The possibility of an anomalous coupling between the top and charm quarks and the gluon field is explored in a model-independent way using an effective Lagrangian that is gauge invariant under a nonlinear realization of SU(3){sub {ital C}}{times} SU(2){sub {ital L}}{times} U(1){sub {ital Y}}. Even for the current 200 pb{sup {minus}1} of integrated luminosity at the Fermilab Tevatron, the new physics scale that strongly modifies the coupling of {ital t}-{ital c}-{ital g} must be larger than about 2.5 TeV if no signal is found within a 3{sigma} confidence limit. For 1 fb{sup {minus}1} of data, this constraint can be pushed up to 3.8 TeV. {copyright} {ital 1996 The American Physical Society.}
