| 英文摘要 | The decay processes from heavy to light pseudoscalar mesons such as pi, K, eta, eta' are studied in a relativistic constituent quark model based on the BS formalism. It is emphasized that the negative energy projector operators's contributions in the BS wavefunctions for light pseudoscalar mesons have to be considered. By taking into account these contributions, the previously encountered difficulties in calculating the decay constants and form factors are found to le removed. All the form factors for transitions such as D --> pi, D --> K, D-s --> K, D-s --> eta, D-s --> eta', B --> pi, B-s --> K are estimated and the branching ratios for these semileptonic decays are calculated. The results of our calculations are consistent with experimental values. |
