The cross sections are of the order of a few picobarn and decrease as the center-of-mass energy increases as s(-n/2) with n = 4.35 +/- 0.14. This result is in agreement with the Nambu-Jona-Lasinio model prediction of n = 3.5 +/- 0.9. In addition, the charmless decay psi(3770) -> phi eta' is searched for by fitting the measured cross sections, yet no significant signal is observed. The upper limit of B(psi(3770) -> phi eta') at the 90% confidence level is determined to be 2.3 x 10(-5).eninfo:eu-repo/semantics/openAccessJona-Lasinio ModelBranching FractionAnnihilationCharmoniumTofArticle1085WOS:0010943007000012-s2.0-85174062988N/A10.1103/PhysRevD.108.052015Q1
