Analysis of the $B\to K_2^{\ast }(1430),a_2(1320),f_2(1270)$ form-factors with light-cone QCD sum rules

Abstract

In this article, we study the $B\to K_2^{\ast }(1430)$, $a_2(1320)$, $f_2(1270)$ form-factors with the light-cone QCD sum rules, where the $B$-meson light-cone distribution amplitudes are used. In calculations, we observe that the line-shapes of the $B$-meson light-cone distribution amplitude ${\varphi }_{+}(\omega )$ have significant impacts on the values of the form-factors, and expect to obtain severe constraints on the parameters of the $B$-meson light-cone distribution amplitudes from the experimental data in the future.
