Abstract
We analyze the decay modes of charmed mesons into two-pseudoscalars in a weak-gauged U(4) L x U (4)R chiral lagrangian model. The calculatio n is free of unknown parameters and only requires as inputs the masses of pseudoscalars and the decay constant of the pion. The general patt ern of the results at leading order compares reasonably well with the experimental data.
