Hi,
to finalize the S/P fixing study we need:
1. Considering better fitting functions to describe the S/P functional
dependence, e.g. a Gaussian fit and determine the systematic
uncertainty
Antonio, what is your estimate: Can we do this until Friday?
2. Do this also on higher purity cuts. Time estimate for that?
3. Apply all reweightings
* Chukwudi has produced with the correct run-wise MC
reweighting new numbers for D**lnu/(Dlnu+D*lnu)
If I interprete the numbers correctly, it is now
O(0.65) instead of 0.55.
* We need to incorporate in the full reweighting also
the run-wise MC reweighting using Wolfgang's VVF tag.
Chukwudi & Antonio: What is your time estimate for that?
Beginning of next week would great since we need to
document it until the end of next week!
4. Wolfgang: I know that you will not read this before next
week but are you able to continue on the fallback
solution next week (18.9.-22.9.)?
* The study on the MC would be very helpful.
* In addition, the fits on data should be repeated with
all reweightings applied.
* If we could also make a comparison of the signal yields
bin-by-bin between the fallback solution and the (S/P)
fixing strategy for equal purity cuts that would give
us also more confidence in case of agreement.
Cheers,
Heiko
