Mixing and lifetimes:
- ΔMs and ΔMd:
- What are the most important remaining systematics in the calculation of ΔB=2 matrix elements?
- What are the prospects for eliminating them?
- Is ΔMd/ΔMs cleaner theoretically than ΔMd?
- What is the real impact of FDs and FD+ measurements on the determination of FBs and FBd?
- Is more experimental accuracy in FDs and FD+ necessary?
- What is the CLEO/BES expected precision for FDs and FD+? At what precision does it become systematics limited?
- Can theory explain all observed lifetime ratios and differences?
- Could new physics be reliably discovered in ΔΓs ?
- What are the prospects for including perturbative and non-perturbative contributions of penguin operators and the non-valence current-current contributions?
- Can anything be learned from a more precise measurement of the Λb/Bd lifetime ratio until then?
- Any plans for unquenched calculations?
- What is the future of CKM constraints from K0 mixing/CP violation? Will the theoretical precision improve?
- Calculations with certain lattice regularizations suggest that BK may be smaller than the canonical quenched result of JLQCD. How seriously should this effect be taken?
- Do we have strong evidence that BK is smaller when the quenched approximation is removed?
- Are we able to reliably match onto chiral perturbation theory to perform the required chiral extrapolation?
- Are there estimates of the systematics associated with the procedure used for including sea quark effects with staggered fermions?
