Query: Semileptonic Decay of $B$ and $D\to K^*_0(1430) \bar{\ell}\nu$ From QCD
  Sum Rule   We calculate $B_{(s)}$, and $D_{(s)}$ to $K^*_0(1430)$ transition form
factors, and study semileptonic decays of $B_{(s)}$ and $D_{(s)}\to K_0^*(1430)
\bar{\ell}\nu$ based on QCD sum rule. Measuring these semileptonic decays with
high statistics will give valuable information on the nature of light scalar
mesons.
