[Olympus] Draft agenda for OLYMPUS collaboration meeting

[Belostotski, Stanislav]

Hi, Jan,
I am afraid as wrongly understood.
Yes ,we are far from  sort of final conclusions.
Yet the lumi study must finally have a goal.
  If one may say anything about possible beam charge asymmetries,
even at the level of estimations right now, what would be harm from that?
That is a critical issue for the whole experiments.
Or you think this is still premature?
With best regards StanB
