Semileptonic Decay of $B$ and $D\to K_0^{\ast }(1430)\bar{\ell }\nu$ From QCD Sum Rule

Abstract

We calculate $B_{(s)}$, and $D_{(s)}$ to $K_0^{\ast }(1430)$ transition form factors, and study semileptonic decays of $B_{(s)}$ and $D_{(s)}\to K_0^{\ast }(1430)\bar{\ell }\nu$ based on QCD sum rule. Measuring these semileptonic decays with high statistics will give valuable information on the nature of light scalar mesons.
