Hi Heiko,
here is a list of what we discussed yesterday:
- we discussed the neutrals problem again looking at the ratio of
branching fractions as a function of mm2. Roberto will make some more
plots extending the scan range and trying different selections.
BAD 540 has some scans on page 94. These look worse than ours.
- we looked at more plots comparing neutral and charged tracks selection
(our and Michaels). Using the old neutrals and Michaels charged tracks
look promising. Roberto might look at this.
Updates:
- Klong: we are waiting for the work from David. He won't present
anything at the tools workshop. Nobody asked him.
- Antonio will produce reduced ntuples (cut on p at 1 GeV), which will
speed up the fitting and reduce the storage
- Antonio is working on the 1d unfolding. It is working but the
acceptance calculating need some more attention.
- neutral/charged B branching fraction. Roberto and Chukwudi looked at
the asymmetry in the MC generator. It should be 4% but they measure
~13%. Could be due to the restricted phase space.
Cheers,
Wolfgang
