1. Mixing/Lifetime Needs
Brad Abbott
(Christos Leonidopoulos)

2. Lifetimes Bs Bd B+
Average B
Lambda_b
B+/B0
We wrote a list of what things we think needs to be addressed
Asked primary authors what they think needs to be done

3. “Task list” For example: Bias in event-event vertexing: Use beam spot
Most analyses need to increase MC statistics and use latest MC
Make sure same size errors for same systematics …
Analysis specific items
Will send out to analyzers

4. Publications Would like to publish lifetime results
Some work necessary to get finalized results and write paper
People moving on to other analyses, students graduating etc.
Who will push these results through?

5. Dimuon data HTFAA extended data: Based on p13 and dimuon triggers
Now have p14 data available with no trigger requirement
Statistically limited on some measurements
Should we rerun over p14 data and repick?
Need to understand how much we will gain
Run over same run range: HTFAA extended and p14 data to see how much we gain. (need a volunteer to do this)

6. Mixing Semileptonic modes is fairly well covered PV: Yuri
Decay length resolution: Christos/Brad
Correction Factor: Ike/Vivek
Event selection: Guennadi
Fitting: Tulika/Hal
Tagging: Xiaojian,Christos,Avdhesh,Jim

7. Delta Md Need to do this before Bs mixing
B->D* mu x : 175 events/pb-1
50 pb-> 8750 events
eD2=0.1 -> 875 tagged events
Wendy has expressed interest in this, could use more people

8. Hadronic modes Rick/Chris working on this No evidence of a signal yet
More people would be welcome
L3 trigger work needed.

9. Sensitivity Semileptonic: yields  Proper time res X
Hadronic yields X Proper time res 
Really need these numbers before we can give estimates that we can believe
