Enhanced Three-Particle Contribution to Electroweak Penguin $B$-Meson Decays

Yong-Kang Huang, Yu-Ming Wang, Xue-Chen Zhao

We compute for the first time the subleading twist correction to the exclusive rare $b\to \left\{s,d\right\}{\ell }^{+}{\ell }^{-}$ decays from the three-particle $B$-meson distri…
