用光锥QCD求和规则分析$B \to K^*_0(1430), a_0(1450)$形状因子

Analysis of the $B \to K^*_0(1430), a_0(1450)$ form-factors with light-cone QCD sum rules

Zhi-Gang Wang, Jun-Fang Li

摘要:

本文将标量介子$K^*_0(1430)$和$a_0(1450)$作为常规的两夸克态,用$B$ -介子光锥QCD求和规则研究了$B \to K^*_0(1430), a_0(1450)$的形状因子,并以此作为基本输入参数研究了半轻子衰变$\bar{B}^0\to a_0^+(1450)l \barν_l $和$B^-\to K_0^{*-}(1430)l\bar{l}$,预测结果可以与实验数据进行比较。

英文摘要:

In this article, we take the scalar mesons $K^*_0(1430)$ and $a_0(1450)$ as the conventional two-quark states, and study the $B \to K^*_0(1430), a_0(1450)$ 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 \barν_l $ and $B^-\to K_0^{*-}(1430)l\bar{l}$, the predictions can be confronted with the experimental data in the future.
