We present the first evidence for B semileptonic decays into the charmed baryon Lambda_c+ based on 420 fb-1 of data collected at the Upsilon(4S) resonance with the BABAR detector at the PEP-II e+e- storage rings. Events are tagged by fully…

Recent results of baryonic B decays from Belle are reported. This study is done by a 78 fb$^{-1}$ data sample, consisting of $85.0 \pm 0.5$ million $B\bar{B}$ pairs, collected by the Belle detector at the KEKB asymmetric energy $e^+e^-$…
We study the baryonic charmonium decays of B mesons, B+ to etac K+ and B+ to J/psi K+, where the etac and J/psi subsequently decay into a p pbar or Lambda Lambdabar pair. We measure the J/psi to p pbar, Lambda Lambdabar anisotropy…
We present an analysis of two-body B decays with a pseudoscalar (P) and an axial-vector meson (A) in the final state using naive factorization. We employ as inputs a limited number of experimental data, i.e. results for the B -> K1 gamma…
We study semileptonic B decay to the exclusive charmless states pi, rho/omega, eta and eta' using the 16 fb-1 CLEO Upsilon(4S) data sample. We find B(B^0 -> pi^-l^+nu) = (1.37 +- 0.15_stat +- 0.11_sys) x 10^-4 and B(B^0 -> rho^- l^+ nu) =…

We present updated measurements of the branching fractions for B0 meson decays to etaK0, etaeta, etaphi, etaomega, eta'K0, eta'eta', eta'phi, and eta'omega, and branching fractions and CP-violating charge asymmetries for B+ decays to…
Rare radiative leptonic decay $B\to l\bar \nu_l \gamma$ is studied in the instantaneous Bethe-Salpeter approach. The results are compared to other relativistic quark model predictions.
A theory of the B -> K \eta' decay is proposed. It is based on the Cabbibo favored b -> \bar{c} c s process followed by a direct materialization of the \bar{c} c pair into the \eta'. This mechanism works due to a non-valence Zweig rule…

This report summarizes the latest experimental results on radiative and electroweak rare B meson decays. These rare decay processes proceed through the flavor changing neutral current processes, and thus sensitive to the postulated new…
We study the charmful three-body baryonic B decays $\bar B\to D^{(*)}N\bar N$: the color-allowed modes $\bar B^0\to D^{(*)+}n\bar p$ and the color-suppressed ones $\bar B^0\to D^{(*)0}p\bar p$. While the $D^{*+}/D^+$ production ratio is…
