How Many D0Ks+- Analyses ?
1. We know that Belle is working on a mixing analysis using D0Ks+- decays.
We might hope they will not have any better Dalitz plot fit than the excellent one in BAD 1237
One imagines they will report ~ 500 fb-1 ?? We need a result soon if we are to be relevant OR Do something significantly different BAIS 06/13 – runs 1-4
2. Some of us think we can try for an even better model – at least we intend to try. Longer term – Runs 1-5 as follow up to hot item above. Modify CLEO (Phys.Rev.D72:012001,2005) to use waves rather than resonances. Attempt to build on excellent work by Antimo (BAD 1293) Explore ways to reduce WS backgrounds and improve time resolution. BAIS ??/?? – runs 1-5
3. Another analysis should follow – possibly at the “discovery level” (if not already reached!)
Yet longer term – Runs 1-6. BAIS ??/?? – runs 1-6

Manpower for #2
Stage one (some of us think we can try for an even better Dalitz plot model – at least we intend to try).
So far – (EB) JC, WMD, DL, DA, (Cin) RA, GM, BM. BAD 1626 in preparation
Mixing Most (or all) above Others welcome!
Time scale Stage one or BUST – winter 2007 Summer 2007 is goal.
