| dc.description.abstract | We observe signals for the decays psi(3770)-> XJ/psi from data acquired with the CLEO detector operating at the CESR e(+)e(-) collider with root s=3773 MeV. We measure the following branching fractions B(psi(3770)-> XJ/psi) and significances: (189 +/- 20 +/- 20)x10(-5) (11.6 sigma) for X=pi(+)pi(-), (80 +/- 25 +/- 16)x10(-5) (3.4 sigma) for X=pi(0)pi(0), and (87 +/- 33 +/- 22)x10(-5) (3.5 sigma) for X=eta, where the errors are statistical and systematic, respectively. The radiative return process e(+)e(-)->gamma psi(2S) populates the same event sample and is used to measure Gamma(ee)[psi(2S)]=(2.54 +/- 0.03 +/- 0.11) keV. | |
