Hoi, I presume the b2u reweighting is implemented in a way that the multiplicity fits can be done as usual? I get the following numbers on anaQA-n00: Sample nocat mult. fit -------------------------------- B 0.0298 0.0213 B0 0.0264 0.0332 B+ 0.0181 0.0182 The B0 is drastically different. Could someone please check these numbers? An confirm that the difference is not due to the implementation? But now to the second part of this mail: At some point someone will calculate the significance between the B0 result of summer and this one ... We have shifted the result of B0 by more than one (statistical) sigma with respect to the previous version (of the BAD)! I am a bit confused (and cannot find all what we had yesterday in Alessio's page anymore, it seems to have been updated). Assuming we MIGHT have a background problem in B0, do we attribute this to signal? If I understand Alessio's webpage correctly, we reweight B0 and B+ separately? But I am not sure what the difference is between row 3 and row 5 in the "Default results" table. I am somewhat concerned by this large shift. Cheers, --U.
