Search for B decays into eta' rho, eta' K*, eta' phi, eta' omega and eta' eta(') at Belle

We report on a search for the exclusive two-body charmless hadronic B meson decays B-> eta' rho, B-> eta' K*, B-> eta' phi, B-> eta' omega and B->eta' eta('). The results are obtained from a data sample containing 535 x 10^6 BBbar pairs that were collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+ e- collider. We find no significant signals and report upper limits in the range 0.5-6.5 x 10^{-6} for all of the above decays.

Baryonic B decays

We summarize recent results of baryonic B decays from Belle and BaBar. The results from Belle are based on 140 /fb and results from BaBar are based on 81 /fb of data collected at the Upsilon(4S) resonance at KEKB or PEPII respectively. We report the results of two- and three-body baryonic B decays as well as searches for pentaquarks. The three-body baryonic B decays display an enhancement in the low mass region, which is not in agreement with general phase space expectations.
