Branching fractions forχcJ→pp¯π0,pp¯η, andpp¯ω

Using a sample of $25.9\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $\ensuremath{\psi}(2S)$ decays acquired with the CLEO-c detector at the CESR ${e}^{+}{e}^{\ensuremath{-}}$ collider, we report branching fractions for the decays ${\ensuremath{\chi}}_{cJ}\ensuremath{\rightarrow}p\overline{p}{\ensuremath{\pi}}^{0}$, $p\overline{p}\ensuremath{\eta}$, and $p\overline{p}\ensuremath{\omega}$, with $J=0$, 1, 2. Our results for $\mathcal{B}({\ensuremath{\chi}}_{cJ}\ensuremath{\rightarrow}p\overline{p}{\ensuremath{\pi}}^{0})$ and $\mathcal{B}({\ensuremath{\chi}}_{cJ}\ensuremath{\rightarrow}p\overline{p}\ensuremath{\eta})$ are consistent with, but more precise than, previous measurements. Furthermore, we include the first measurement of $\mathcal{B}({\ensuremath{\chi}}_{cJ}\ensuremath{\rightarrow}p\overline{p}\ensuremath{\omega})$.
