Description

We report our works on calculation of exclusive B-meson decays to charmed mesons. In lattice simulation, we use the Oktay-Kronfeld action for the bottom and the charmed quark and HISQ action for the light quarks. We report how discretization error in the lattice simulation can be controlled in systematic way.
