Resumo

We describe a search for ψ(3770) decay to two-body non-D¯¯¯D final states in e+e− data produced by the CESR collider and analyzed with the CLEO-c detector. Vector-pseudoscalar production ρ0π0, ρ+π−, ωπ0, ϕπ0, ρη, ωη, ϕη, ρη′, ωη′, ϕη′, K*0¯¯¯¯¯K0, and K*+K− is studied along with that of b1π (b01π0 and b+1π−) and π+π−π0. The largest amount of disagreement between the expected rate for e+e−→γ∗→X and that for e+e−→X at √s=3.773 GeV is found for X=ϕη, at an excess cross section of (2.4±0.6) pb [Γψ(3770)ϕη=(7.4±1.6) keV], and a suggestive suppression is seen for π+π−π0 and ρπ. We conclude with form factor determinations for ωπ0, ρη, and ρη′.Received 9 September 2005DOI:https://doi.org/10.1103/PhysRevD.73.012002©2006 American Physical Society
