Abstract
Using data accumulated with the CLEO detector corresponding to an integrated luminosity of L = 5.63 pb(-1) on the peak of the psi(2S) [3.08x10(6) psi(2S) decays] and 20.70 pb(-1) at root s = 3.67 GeV, we report first measurements of the branching fractions for the following 13 decay modes of the psi(2S): eta 3 pi, eta(')3 pi, rho K+K-, K(+)K(-)pi(+)pi(-)pi(0), 2(K+K-), 2(K+K-)pi(0), rho p (p) over bar, p (p) over bar pi(+)pi(-)pi(0), eta p (p) over bar, p (p) over barK(+)K(-), Lambda(Lambda) over bar pi(+)pi(-), Lambda pK(+), and Lambda(p) over barK(+)pi(+)pi(-), and more precise measurements of 8 previously measured modes: 2(pi(+)pi(-)), rho pi(+)pi(-), 2(pi(+)pi(-))pi(0), omega pi(+)pi(-), K(+)K(-)pi(+)pi(-), omega K+K-, phi K+K-, and p (p) over bar pi(+)pi(-). We also report new branching fraction measurements of phi pi(+)pi(-) and omega p (p) over bar and upper limits for eta pi(+)pi(-), eta K+K-, and phi p (p) over bar. Results are compared, where possible, with the corresponding J/psi branching ratios to provide new tests of the 12% rule.
