[Sbs_software] [EXTERNAL] Online Asymmetry Analysis

[Sean Jeffas]

Hi All,

A couple weeks ago I presented on different ideas for monitoring our
asymmetry faster than waiting for 10's of millions of events to be
collected. Below I have updated my slides with some new information.

As I have shown here we can combine all pion singles in BB and get a
statistically significant asymmetry on the order of 6M events. For GEN4
this would require about 2 days of data collection at our current rates.
Therefore I think it would be reasonable to use this method to check the
asymmetry every few days. This would therefore be expert driven and it
would be helpful to have a quick check occasionally to make sure things are
looking reasonable, although it is far from catching any issues in real
time. Let me know if anyone has any thoughts or comments.

Best,
Sean
