Appel, J A

A series of heavy flavor experiments is being performed at the Fermilab Tagged Photon Laboratory. These experiments make use of accurate charged particle tracking, including precise vertex determinations, in an open geometry forward spectrometer. The global transverse energy trigger has high acceptance for all heavy flavor decay modes and allows a wide variety of questions to be addressed. Some of the results for the completed charm photoproduction experiment, especially production dynamics and relative branching ratios, have been selected for presentation. Their selection is due to their relevance to questions fundamental to QCD, the topic of this workshop. Other results (e.g., on charm particles lifetimes, mixing, Cabibbo single and doubly suppressed decays, etc.) have appeared already or are about to appear. The current experiment, charm hadroproduction, is also described and its status presented. Finally, plans for future efforts, including beauty hadroproduction, are summarized. 5 refs., 13 figs., 4 tabs.
