Hi Roberto, > there is a new update of > http://www.slac.stanford.edu/~sacco/efficiency/eff.html, where I added > separate plots for charged and neutral Bs and a couple of columns to the > table showing the efficiency with the cut on integrated purity. the B0 qtot distribution looks strange, can you have a look into it? another point: unfortunately rerunning the old production without killing and smearing does not fix the disagreement but remember that the lepton ID killing is still there since it was done at Beta level. You should run IbuNtpDump Beta jobs to remove all PID killings. Daniele
