Preliminary look at D0  P P (p0) decays S. Davis, C. Plager, M. Selen April/6/2001
Look for 6 D0 decay modes:
K+p-, p+p-, K+K-, K+p-p0, p+p-p0, K+K-p0
Demand that D0 comes from D*+  D0p+

10. Partial To Do List Efficiency & Yields in BR measurements.
Lots of work for Dalitz analyses.
Endless systematics !
We are just getting started !
