Excited heavy mesons decay form factors in light cone QCD

The form factors of B1→π and D1→π transitions, where B1(D1) is the 1+ P-wave Q̄γνγ5q meson state, are calculated in the framework of the light cone QCD. Furthermore, these form factors are compared with the pole dominance model prediction using the values of the strong coupling constants gB1B∗π and gD1D∗π, and a good agreement between these two different descriptions is observed.
