Search for Rare b \to d\ell^+\ell^- Transitions at Belle

We present the results of a search for the b \to d\ell^+\ell^- flavor-changing neutral-current rare decays B^{+, 0} \to (\eta, \omega, \pi^{+,0}, \rho^{+, 0}) e^+e^- and B^{+, 0} \to (\eta, \omega, \pi^{0}, \rho^{+}) \mu^+\mu^- using a 711 fb^{-1} data sample that contains 772 \times 10^{6} B\overline{B} events. The data were... Show more
