Abstract

The moving NRQCD (mNRQCD) formalism facilitates the simulation of heavy meson decays at large recoil. We present preliminary results for a number of quantities including the energy splittings and the $B$ meson decay constant that demonstrate that the formalism is accurate over a range of momenta.
