| 英文摘要 | Decays of the psi(2s) into vector plus pseudoscalar meson final states have been studied with 14x10(6) psi(2s) events collected with the besii detector. branching fractions of psi(2s)-->phieta, phieta('), and omegaeta('), and upper limits of psi(2s)-->phipi(0) and omegaeta are obtained: b(psi(2s)-->phieta)=(3.3+/-1.1+/-0.5)x10(-5), b(psi(2s)-->phieta('))=(3.1+/-1.4+/-0.7)x10(-5), and b(psi(2s)-->omegaeta')=(3.2(-2.0)(+2.4)+/-0.7)x10(-5); and b(psi(2s)-->phipi(0))<0.40x10(-5), and b(psi(2s)-->omegaeta)<3.1x10(-5) at the 90% c.l. these results are used to test the perturbative qcd "12% rule." |
