摘要：

We modify a chiral effective lagrangian, recently suggested to describe interactions of the light pseudoscalars with mesons containing a heavy quark, so as to incorporate light vector resonances, such as rho, etc. The modification uses the hidden gauge symmetry approach. As a preliminary example we present an application to the semileptonic D --> K* decay.
