By fitting these energy-dependent cross sections, we search for the excited psi states psi(4160) and psi(4415), and the vector charmonium-like states psi(4230), psi(4360), and psi(4660). No evidence for these is observed and the upper limits on the branching fractions of these states decaying into -Lambda+.. are set at the 90% confidence level.eninfo:eu-repo/semantics/openAccessE(+)-E(-) ExperimentsQuarkoniumMeasurement of e+e-?pK- ? plus c.c. cross sections between 4.009 GeV and 4.951 GeVArticle12WOS:0011273196000012-s2.0-85179731542N/A10.1007/JHEP12(2023)027Q2
