Pi and PiPi Decays of Excited D Mesons
T. A. Lahde, D. O. Riska
The and decay widths of the excited charm mesons are calculated using a Hamiltonian model within the framework of the covariant Blankenbecler-Sugar equation. The pion-ligh…

Pion Rescattering in Two-Pion Decay of Heavy Quarkonia
T. A. Lahde, D. O. Riska
The role of pion rescattering in decay of radially excited heavy quarkonia modeled in terms of a coupling, is investigated within the framework of the covariant Blankenb…

Two-Pion Decay Widths of Excited Charm Mesons
T. A. Lahde, D. O. Riska
The widths for decay of the L=1 charm mesons are calculated by describing the pion coupling to light constituents quarks by the lowest order chiral interaction. The wavefuncti…
