We find no significant signal and set upper limits on sigma(e(+)e(-) -> pi X-0(3872)gamma) . B(X(3872) -> pi(+)pi(-)/J/psi) and sigma(e(+)e(-) -> pi(0)Z(c)(4020)(0)). B(Z(c)(4020)(0) -> X(3872)gamma) . B(X(3872) -> pi(+)pi(-) J/psi) for each energy point at 90% confidence level, which is of the order of several tenths pb.eninfo:eu-repo/semantics/openAccessTofArticle2-s2.0-8510929858810.1103/PhysRevD.104.0120011Q1104Q1WOS:000670702100001
