Progress report on testing robustness of the Newton method in data analysis on 2-point correlation function using a MILC HISQ ensemble

We report recent progress in data analysis on the two point correlation functions which will be prerequisite to obtain semileptonic form factors for the B (ₒ) D (ₒ) decays. We use a MILC HISQ ensemble for the measurement. We use the HISQ action for light quarks, and the Oktay-Kronfeld (OK) action for the heavy quarks (b and c). We used a sequential Bayesian method for the data analysis. Here we test the new fitting methodology of Benjamin J. ~Choi in a completely independent manner.
