Bs oscillations
- Inclusive analyses : l - l; l - Qjet
- Semi - exclusive : Ds(l) - multitag
- High frequency + fs small + difficult Ds reconstruction:
- no measurement ! ( ... yet )
- How to put a limit :
- reliable ( = safe from statistical fluctuation)
- include systematics
- easy combination of analyses/experiments
- How to push the limit exploting:
- correlation among tags
- event by event discriminators
- Contributions from LEP only ( at present )
- Most Results are still Preliminary (P)
