Physical Review D 74,1 (2006) 012005;
Using the current world's largest data sample of psi(3770) decays, we present results of a search for the non-D (D) over bar decay psi(3770)->(KSKL0)-K-0. We find no signal, and obtain an upper limit of sigma(e(+)e(-)->psi(3770)->(KSKL0)-K-0)< 0.07 pb at 90% confidence level (CL). Our result tests a theoretical prediction for the upper bound on B(psi(3770)->(KSKL0)-K-0) based on a charmonia-mixing model.
