Ciao Kerstin, > I see in VubXlnu.cc that there is some "pi0 killing" going on when > the kinematic variables for the soft pi- partial D* reco are > computed (killing as in they are not computed for every pi0). This > killing probability is a function of the soft pi0 momentum. Why is > this done and where do the parameter (and the parametrization) of > this function come from? concerning this, we have introduced the killing since we use a pi0 list to do the D* partial reconstruction. We took the recipe from the Neutral Reconstruction AWG page (for R18, of course, given that nothing was ever updated to newer releases): http://www.slac.stanford.edu/BFROOT/www/Physics/Analysis/AWG/Neutrals/validation/recipie18.html All the best, Roberto
