$\psi \mathrm{}\left(2S\right)\mathrm{}$ two- and three-body hadronic decays

We report measurements of branching fractions for $\psi \mathrm{}\left(2S\right)\mathrm{}$ decays into $\omega {\pi }^{+}{\pi }^{-},$ $b_1\pi ,$ $\omega f_2\mathrm{}\left(1270\right),$ $\omega K^{+}{K}^{-},$ $\omega p\overline{p},$ $\phi {\pi }^{+}{\pi }^{-},$ $\phi f_0\mathrm{}\left(980\right),$ $\phi K^{+}{K}^{-},$ and an upper limit for $\phi p\overline{p}$ final states based on a data sample of $(4.02\mathrm{}\pm 0.22)\times {10}^6\psi \mathrm{}\left(2S\right)\mathrm{}$ events collected with the BESI detector at the Beijing Electron-Positron Collider. The branching fractions for $b_1\pi$ and $\omega f_2\mathrm{}\left(1270\right)\mathrm{}$ update previous BES results, while those for other decay modes are first measurements. The ratios of $\psi \mathrm{}\left(2S\right)\mathrm{}$ and $J/\psi$ branching fractions are smaller than what is expected from the $12\%$ rule by a factor of 5 for $\omega f_2\mathrm{}\left(1270\right)\mathrm{}$ and by a factor of 2 for $\omega {\pi }^{+}{\pi }^{-},$ $\omega p\overline{p},$ and $\phi K^{+}{K}^{-},$ while for other studied channels the ratios are consistent with expectations within errors.
