Abstract

In this work, we predict the light hadronic decay channels Y(4230)ΛΛˉY(4230)\to\Lambda\bar{\Lambda} and ΞΞˉ+\Xi^-\bar{\Xi}^+ when treating the Y(4230)Y(4230) as a vector charmonium state. By the hadronic loop mechanism, the branching ratios of the Y(4230)ΛΛˉY(4230)\to\Lambda\bar{\Lambda} and ΞΞˉ+\Xi^-\bar{\Xi}^+ processes are calculated. In addition, we discuss the possibility of carrying out the search for the signal of the Y(4230)Y(4230) through ΛΛˉ\Lambda\bar{\Lambda} and ΞΞˉ+\Xi^-\bar{\Xi}^+ channels from the e+ee^+e^- annihilation. Assuming Y(4230)Y(4230) exist in ΛΛˉ\Lambda\bar{\Lambda} and ΞΞˉ+\Xi^-\bar{\Xi}^+ channel, we also present the time-like electromagnetic form factors (EMFFs) at s=mY(4230)\sqrt{s}=m_{Y(4230)}.
