CP VIOLATION, TOP QUARKS AND THE TEVATRON UPGRADE

In order to observe a signal of possible CP violation in top-quark cou plings, we study top-quark production and decay under the conditions o f the Tevatron upgrade. Transverse energy asymmetries sensitive to CP violation are defined. Applying the recently proposed optimal method, we calculate the statistical significance for the direct observation o f CP violation in the production and subsequent decay of top quarks. W e focus on observables sensitive to absorptive contributions to CP-vio lating form factors. (C) 1997 Elsevier Science B.V.
