EXTRACTING ANOMALOUS GLUON-TOP-QUARK EFFECTIVE COUPLINGS AT THE SUPERCOLLIDERS

Production of ttBAR by gluon fusion followed by t --> bW+, tBAR --> bW-, and W+/- --> e+/- v(e)(v(e)BAR) is studied to extract the CP-violating chromoelectric dipole moment form factor of the top quark. The fact that the spin of the top quark, in its rest frame, is in the direction of the e+ momentum facilitates the analysis. Expressions for the differential cross section and decays arc given. We find that at the Superconducting Super Collider or CERN Large Hadron Collider, it is possible to put a limit of 10(-20)g(s) to 10(-19)g(s) cm on these effective couplings through the use of "optimal observables." Naive observables such as simple triple product correlations are typically an order of magnitude less effective.
