More on Symmetries in Heavy Quark Effective Theory
Ashok Das, V. S. Mathur
We present a general classification of all normal and ``chiral" symmetries of heavy quark effective theories. Some peculiarities and conondrums associated with the ``chiral" symmet…
Annihilation Diagrams in Two-Body Nonleptonic Decays of Charmed Mesons
P. Bedaque, A. Das, V. S. Mathur
In the pole-dominance model for the two-body nonleptonic decays of charmed mesons and , it is shown that the contributions of the intermediate…
Two-Body Nonleptonic Decays of Charmed Mesons
P. Bedaque, A. Das, V. S. Mathur
Two-body nonleptonic decays of charmed mesons are studied on the basis of a simple pole-dominance model involving the vector, pseudoscalar and axial-vector meson poles.
Nonleptonic Decays of Charmed Mesons into two Pseudoscalar Mesons
Ashok Das, Vishnu Mathur
We investigate the nonleptonic decay of charmed meson into two pseudoscalar mesons using the vector--dominance model, and compare the results with those obtained from the factoriza…
