We present here the preliminary MARK III results on a search for non-charm decays of the (Psi)(double prime) resonance. In particular, we search for the decay (Psi) (yields) (phi) + X, in analogy with the recently reported CLEO measurement of Y(4S) (yields) J/(Psi) + X. We see (phi)'s produced at a center of mass energy of 3.77 GeV at a rate which exceeds that from continuum production. However, any attribution of this inclusive (phi) production to direct (Psi)(double prime) decay must await the completion of our background calculations of (phi)'s which come from the decays of radiatively-produced J/(Phi) and (Psi)(prime) present in the 3.77 GeV data. 4 refs., 1 fig., 2 tabs.

This report presents the results of a set of feasibility studies for observing D(sup 0)--(bar D)(sup 0) mixing and CP violation in the proposed high luminosity (tau)-charm factory. These studies are not yet complete, but clear general conclusions can already be drawn. In particular, a year of running with 10(sup 33) luminosity would allow observation of D(sup 0)--(bar D)(sup 0) mixing at the level of 10(sup (minus)4) to 10(sup (minus)5), consistent with standard model expectations, while CP violation in the D system could be probed at the 10(sup (minus)2) level. 7 refs., 3 figs., 4 tabs.

D sup 0 - /bar D/ sup 0 mixing, the extent to which the flavor eigenstate D sup 0 is not a mass eigenstate, is expected to be quite small in the standard model. Consequently, any evidence for the existence of D sup 0 - /bar D/ sup 0 mixing at the currently experimentally accessible levels would indicate the need for explanations invoking new physics. In this report, I will review the current experimental situation. 8 refs., 8 figs. (ERA citation 14:016328)
