Hi, Urs discovered a bug in both .dec files BB_BrecoCocktail_Xulnu.dec (mix) and BB_BrecoCocktail_Xulnu.dec (not reson.). Basically the BR D+->kpipi is a factor 2 higher (only for D+ and not D-). Then we will have an eccess of reconstructed B0->D+X (I guess ~60%). This has not dramatic consequences in the recoil. The only problem is that we will have a charge asymmetry due to the fact that the D- are fine (but I think that we are not sensitive to this kind of systematics). Anyway I fixed the bug and committed. Since SP4 production has not started yet, it will use the correct files. The MC produced by Concezio has this problem. Daniele
