Charm2000: A >10^8-charm experiment for the turn of the millennium

I discuss the physics reach of a fixed-target charm experiment which can reconstruct >10^8 charm decays, three orders of magnitude beyond the largest extant sample. Such an experiment may run at Fermilab shortly after the Year 2000. In addition to "programmatic" charm physics such as spectroscopy, lifetimes, and tests of QCD, this "Charm2000" experiment will have significant sensitivity to new physics in the areas of CP violation, flavor-changing neutral-current and lepton-number-violating decays, and mixing, and could observe direct CP violation in Cabibbo-suppressed decays at the level predicted by the Standard Model.

Production of Charm, Charmonium, and Beauty in 800$\,$GeV Proton-Nucleon Collisions

Some recent results from the Fermilab fixed-target experiment E789 on production of charm, charmonium, and beauty are summarized and compared to model predictions. The data indicate that heavy-quark and quarkonium production are not yet entirely understood. The largest discrepancy concerns the rate of $ψ^\prime$ production, which is a factor $\approx$25 above expectations.

High-Impact Charm Physics at the Turn of the Millennium

I review the sensitivities achieved by and projected for fixed-target charm experiments in CP violation, flavor-changing neutral-current and lepton-number-violating decays, and mixing, and I describe the Charm2000 experiment intended to run at Fermilab in the Year ~2000. If approved, Charm2000 will in many of these areas exceed the sensitivities projected for a Tau/Charm Factory, but the Tau/Charm Factory retains certain qualitative advantages.

Physics of An Ultrahigh-Statistics Charm Experiment

We review the physics goals of an ultrahigh-statistics charm experiment and place them in the broader context of the community's efforts to study the Standard Model and to search for physics beyond the Standard Model, and we point out some of the experimental difficulties which must be overcome if these goals are to be met.

An Ultrahigh-Statistics Charm Experiment for the Year $\sim2000$

After reviewing the motivation for high-statistics charm studies, we describe a fixed-target experiment capable of reconstructing $>10^8$ charm decays. Such an experiment can test the Standard Model and probe non-Standard physics through sensitive searches for such phenomena as D0 mixing, CP violation, and FCNC decays.
