摘要：

We describe a search for psi(3770) decay to two-body non-D (D) over bar final states in e(+)e(-) data produced by the CESR collider and analyzed with the CLEO-c detector. Vector-pseudoscalar production rho(0)pi(0), rho(+)pi(-), omega pi(0), phi pi(0), rho eta, omega eta, phi eta, rho eta', omega eta', phi eta', K-*0(K-0) over bar, and K*K-+(-) is studied along with that of b(1)pi (b(1)(0)pi(0) and b(1)(+)pi(-)) and pi(+)pi(-)pi(0). The largest amount of disagreement between the expected rate for e(+)e(-)->gamma*-> X and that for e(+)e(-)-> X at root s = 3.773 GeV is found for X = phi eta, at an excess cross section of (2.4 +/- 0.6) pb [Gamma(psi(3770))(phi eta)=(7.4 +/- 1.6) keV], and a suggestive suppression is seen for pi(+)pi(-)pi(0) and rho pi. We conclude with form factor determinations for omega pi(0), rho eta, and rho eta(').
