We present a physical interpretation and discuss the relation to results obtained from Perturbative QCD and Local Hadron Parton Duality (LPHD). We also present implications for B$π$ correlations and the possibility to use these as a tag to study CP violation in B decays.High Energy Physics - Phenomenologytext
