Predicted Λ(Λ)over-bar and Ξ-(Ξ)over-bar+ decay modes of the charmoniumlike Y(4230)

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