Description

We determine hopping parameters of the Oktay-Kronfeld (OK) action for charm and bottom quarks. We use $N_f=2+1+1$ MILC HISQ ensembles (with $a\approx0.12$fm, $am_l=0.0102$, $am_s=0.0509$ and $am_c=0.635$). As a key ingredient, we compute the masses of pseudoscalar and vector mesons $B_s^{\ast}$, $D_s^{\ast}$ and their hyperfine splittings; the valence light quark is simulated with HISQ action. We also monitor the inconsistency parameters to confirm the improvement.
