Description
We present our current progress on the lattice calculation of decay constants for $B_{(s)}$, $D_{(s)}$ mesons using sequential Bayesian method and the Oktay-Kronfeld (OK) action for the charm and bottom quarks (valence quarks). Here, the masses of charm and bottom quark are determined non-perturbatively. For the light spectator quarks (up, down and strange), we use HISQ action. Lattice calculation is done on MILC HISQ a12m220 ensemble ($N_f=2+1+1$ flavors). $f_{B_s} / f_B$ and $f_{D_s} / f_D$, the flavor $SU(3)$ symmetry breaking ratio, are presented. They are independent of the renormalization constants for the axial current.
