Hi all,
after debugging the code (now I know that's impossible to have the
duplicates killing and the fit running at the same time) now there's a new
tag where the reweighting has been implemented and it's working:
ale-06082002
Attention to the fact that also the recoilDSys has changed:
a bug fix and some modification in order to fix BRs to PDG values has been
implemented.
With the -Sys option you can switch on the 'random' reweighting:
BR are fixed to a random value extracted accordingly to a gaussian
distribution with mean and sigma from PDG.
With -Rew option you simply fix the BR values to the PDG ones.
The weight to apply to each vcb event is calculated as the product of the
weights for B->semil decays and for D-> decays.
In this way we have
B->D*lnu (only weight from B) = wB
B->Dlnu (weight from B * weight from D) = wB*wD
This whole procedure has to be tested and checked for bugs (correct
values for all BR, correct implementation of reweighting).
Let me know any comment or question.
Cheers,
Alessio
