Evidence for $B^0 \to \chi_{c1} \pi ^0$ at Belle

open access: yes, 2008
We present a measurement of the branching fraction for the Cabibbo- and color-suppressed $B^0 \to \chi_{c1}\pi^0$ decay based on a data sample of $657\times 10^6$ $B\bar B$ events collected at the $\Upsilon(4S)$ resonance with the Belle detector at the ...

A Study of B+->p pbar K+ and a Search for a Theta*++ Pentaquark Candidate in B Decay

open access: yes, 2004
A study of the decay B+->ppbarK+ is performed using 81fb-1 of data collected at the Upsilon(4S) with the BaBar detector at PEP-II. The branching fraction of B+->ppbarK+ is measured to be (6.7+/-0.9+/-0.6)x10^-6.

Measurement of the branching fractions of psi(2S) -> 3(pi+pi-) and J/psi -> 2(pi+pi-)

open access: yes, 2005
Using data samples collected at sqrt(s) = 3.686GeV and 3.650GeV by the BESII detector at the BEPC, the branching fraction of psi(2S) -> 3(pi+pi-) is measured to be [4.83 +- 0.38(stat) +- 0.69(syst)] x 10^-4, and the relative branching fraction of J/psi ->
