Description

We report recent progress in data analysis on the correlation functions

of the semileptonic decays $B_{(s)}\to D_{(s)}\ell \nu$ form factors.

The data set of measurement is MILC HISQ ensemble for the light quarks

and Oktay-Kronfeld (OK) action for the heavy quarks: a12m310 ($N_f=2+1+1$ flavor)

We used sequential Bayesian method for the analysis and adopted Newton

method to find better initial guess.
