Hi all, starting from the disagreement shown by Ajit in the lepton spectrum for the wrong sign events for the mode B+->D0pi with D0->Kspipi we finally discovered the bug. In recoilNtp the flavor and the charge of the B is assigned looking at the flavor of the daugther D meson. Unfortunately for D0->Kspipi the flavor is correct only in 50% of the cases. Then the charge and the flavor of the B+ reconstructed in a mode with D0->Kspipi were crap. This bug should affect B+->D0X with D0->Kspipi (all X systems) in the following ways: - total charge is wrong - lepton spectrum (applying the charge correlation) is wrong - all variables that present differences between right sing and wrong sing could be affected I am going to fix the bug (charge and flavor for B+ will be calculated adding up the charge of all the daughters). Then it should be interesting to see how the measurement for B+ will change and how the comparison data-mc will look like (remember that the comparison for B+ was usually not so good). Daniele and Ric
