[Clas12_verystrange] meeting minutes

[Lei Guo]

A few items were discussed.
Simulation:
Will produced the acceptance of XI(1820) ( K+K+K- (Lambda) and K+K+K- 
proton (pi-) channel) and Omega-  (3K and 4K) channels, for +-25%,  
50%, 75&, and full fields.
For the Xi(1820), there is less dependence on the field (when  
reversed).  There is also no order of magnutide difference as opposed  
to the omega- 4K channel case, when we move from half field to full  
field.
For the Omega-, there is some interesting results. The reverse field  
is even better than half normal field. If this can be verified by  
Diane (expected next week), it is something we can definitely make use  
of.
For the Background, Mike has generated 100M events, and will dial it  
to 10B events next week. These events will be analyzed for the Xi-, Xi- 
(1820) and Omega- channels.  Once these results are in (and verified),  
they will be incorporated into the proposal.
We also discussed PID issues. Eugene raised the point that there is no  
reliable reconstruction, so we should concentrate on the  
misidentification probability. ANd Mike will look further into that.
