No significant signals are observed and the upper limits of the product branching fractions B(psi(3770) ->gamma X(3700)) center dot B(X(3700)-> eta eta') and B(psi(3770) ->gamma X(3700)) center dot B(X(3700) -> pi(+)pi(-)J/psi) are determined at the 90% confidence level, for the narrow X(3700) with a mass ranging from 3710 to 3740 MeV/c(2), which are from 0.9 to 1.9(x10(-5)) and 0.9 to 3.4(x10(-5)), respectively.eninfo:eu-repo/semantics/openAccessCross-SectionE(+)E(-)J/Psi-D(D)Over-BarStateArticle1085WOS:0010943029000012-s2.0-85178239268N/A10.1103/PhysRevD.108.052012Q1
