Couplings of pions to higher positive parity heavy mesons

We evaluate the couplings of pions in the transitions of positive parity he avy mesons, (1(+), 2(+)) and (0(+), 1(+)), to negative parity ones (0(-), 1 (-)) using a technique which is not limited to the soft-pion limit. This is made through a constituent quark-meson model (the CQM model) where the amp litudes are obtained by quark loops with mesons on the external lines. The results are in good agreement with experimental data.
