Branching fractions for χcJ→pp̄π0, pp̄η, and pp̄ω

Journal article

Using a sample of 25.9×106 ψ(2S) decays acquired with the CLEO-c detector at the CESR e+e- collider, we report branching fractions for the decays χcJ→pp̄π0, pp̄η, and pp̄ω, with J=0, 1, 2. Our results for B(χcJ→pp̄π0) and B(χcJ→pp̄η) are consistent with, but more precise than, previous measurements. Furthermore, we include the first measurement of B(χcJ→pp̄ω). © 2010 The American Physical Society.
