2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/178673We report measurements of branching fractions for psi(2S) decays into omega pi pi, b1 pi,omega f2(1270),omega KK, omega p pbar, phi pi pi, phi f0(980),phi KK, and an upper limit for phi p pbar final states based on a data sample of 4 X 10^6 psi(2S) events collected with the BESI detector at the Beijing Electron-Positron Collider. The branching fractions for b1 pi and omega f2(1270) update previous BES results, while those for other decay modes are first measurements. The ratios of psi(2S)and J/psi branching fractions are smaller than what is expected from the 12% rule by a factor of five for omega f2(1270),by a factor of two for omega pi pi, omega p pbar, and phi KK, while for other studied channels the ratios are consistent with expectation within errors.9 pages,12 figures and 1 tableHigh Energy Physics - Experimenttext
