Parameter--free calculation of $D\to PP$ in a weak--gauged $U(4{)}_L\otimes U(4{)}_R$ Chiral Lagrangian Model

F. J. Botella, S. Noguera, J. Portolés

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 calculation is free of unknown parameters and on…
