Hi all,
here's some material for today's meeting:
1)I've tried to play a bit with Kl stuff.
Thos are three data-MC comparisons for the energy of those neutrals that
have the largest likelihood to be Kl:
..as it is (no correction applied)
http://www.slac.stanford.edu/~asarti/recoil/devel/KLstu/nu/comparison5mxminpileptoncuts.ps
applying a correction (on MC)::
newE(g) = E(g)*(mean_data(enr.)/mean_MC(enr.))
http://www.slac.stanford.edu/~asarti/recoil/devel/KLstu/nurewsh/comparison5mxminpileptoncuts.ps
applying a correction (on MC)::
newE(g) = E(g)+(mean_data(enr.)-mean_MC(enr.))
http://www.slac.stanford.edu/~asarti/recoil/devel/KLstu/nurewsh/comparison5mxminpileptoncuts.ps
The first correction method seems more powerful
than the second one:
there are suggestions for different correction procedures?
Once we agree on wich correction we need to use to reweight
our MC I'll prepare the anaRecoil code in such a way that
the energy of those neutrals that have a KL likelihood > 0
energyGam[i] *= f(corr_factor);
can be corrected for the given factor and Urs/whoever else
can rerun the analysis rootfile production.
2)I've played a bit with the m_b mass that can be extracted by
our datasample and here's the output of my very firt study:

Are you going to call me in Ferrara?
