Analysis of the $B\to K_0^{\ast }(1430),a_0(1450)$ form-factors with light-cone QCD sum rules

Abstract

In this article, we take the scalar mesons $K_0^{\ast }(1430)$ and $a_0(1450)$ as the conventional two-quark states, and study the $B\to K_0^{\ast }(1430),a_0(1450)$ form-factors with the $B$-meson light-cone QCD sum rules, then take those form-factors as basic input parameters to study the semi-leptonic decays ${\bar{B}}^0\to a_0^{+}(1450)l{\bar{\nu }}_l$ and $B^{-}\to K_0^{\ast -}(1430)l\bar{l}$, the predictions can be confronted with the experimental data in the future.
