Pi and PiPi Decays of Excited D Mesons

Abstract

The $\pi$ and $\pi \pi$ decay widths of the excited charm mesons are calculated using a Hamiltonian model within the framework of the covariant Blankenbecler-Sugar equation. The pion-light constituent quark coupling is described by the chiral pseudovector Lagrangian.
