Pseudo-scalar heavy meson decays in covariant light front dynamics
- 24 Downloads
We investigate the leptonic decay amplitude of heavy pseudo-scalar mesons as well as the B to D transition amplitude in the heavy quark limit, using the covariant formulation of light-front dynamics. The explicit rotational invariance of this formalism enables us to recover the analytic results obtained for these processes using the Bakamjian–Thomas construction in equal time dynamics, in the limit of an infinitely heavy mass. The covariant formulation provides a very convenient and coherent framework for calculating the 1/m corrections.
