$B_{(s)}to D_{(s)}$ semileptonic decays with NRQCD-HISQ valence quarks


Abstract in English

We present a calculation of the form factors, $f_0$ and $f_+$, for the $B_{(s)} to D_{(s)}$ semileptonic decays. Our work uses the MILC $n_f=2+1$ AsqTad configurations with NRQCD and HISQ valence quarks at four values of the momentum transfer $q^2$. We provide results for the chiral-continuum extrapolations of the scalar and vector form factors.
