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: http://www.slac.stanford.edu/~asarti/recoil/myThesis/mbmeas.html Are you going to call me in Ferrara? alessio ______________________________________________________ Alessio Sarti Universita' & I.N.F.N.
