We evaluate the couplings of pions in the transitions of positive parity heavy 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 amplitudes are obtained by quark loops with mesons on the external lines. The results are in good agreement with experimental data.

Abstract
We evaluate the couplings of pions in the transitions of positive parity heavy 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 amplitudes are obtained by quark loops with mesons on the external lines. The results are in good agreement with experimental data.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
