> 4) Table 9: what is the reason for the large contributions of K+- for B+- ?? > Hi all, I've spent a bit of time trying to understand the reasons for such behaviour. I've obtained the 'inclusive' breakdown for the various categories and they still show the big disagreement. I've also removed the analysis cuts and redone the study and the discrepancy is still there. So I've tried to look (with Ric's help :)..) once again at the physical arguments that are supporting such behaviour (excess of B+ -> K+). >From the PDG we got: Gamma D+/- D0 tot 0.946ps-1 2.41ps-1 semilep 0.168ps-1 0.163ps-1 K0 0.57ps-1 1.01ps-1 K+/- 0.29ps-1 1.35ps-1 Given that B+ -> mostly in D0 while B0 -> mostly in D+/- I think that we've found the source of what we see (B+ -> K+ >3 times higher than B0 -> K+). The relation btw the different BR for D0 and D+ in K+ and K0 can be found 'counting' the quarks involved in D decays and pointing out that D0 and D+ decays in K+ differs also for a colour factor (D+->K+ being suppressed). That might be the reason of the results obtained/showed in table 9. Adding a small comment in the BAD clarifying that can help the reader understanding the numbers quoted: I'll add it if there are no other doubt/questions remaining on that issue. Commenst are welcomed. Cheers, Alessio
