$a_0(1450)$-state twist-2 light-cone distribution amplitude moments within QCD sum rules and its implication in ${\bar{B}}^0\to a_0(1450{)}^{+}{\ell }^{-}{\bar{\nu }}_{\ell }$ decays

Ya-Lin Song, Yin-Long Yang, Yan-Ting Yang +4

Based on longstanding puzzle for the structure of light scalar meson, it is meaningful to make a deep research for its property in different decay processes especially in the botto…
