Angular Scaling of Jets as a b, c Tagger

The angular correlation of jets is a shape observable asks for the the jet substructre. We used the derivative of the angular correlation and we found that its avarage is a higher for b quark shower jets than c quark. But for jet by jet analysis their is many flactuation for Pythia analysis and LHC data. So in our analysis the anguler correlation is not a discriminator observable.
