英文摘要In this work, we investigate the open-charm decay process psi -> Lambda(c)(Lambda) over bar (c) via the hadronic loop mechanism for vector charmonia above Lambda(c)(Lambda) over bar (c) threshold. The branching ratios of these vector charmonium states to Ac Furthermore, for the predicted higher vector charmonia above 4.7 GeV, the branching ratios B[psi(nS) -> Lambda(c)(Lambda) over bar (c)] with n = 7, 8, 9 are found to be of the order of magnitude of 10(-4) - 10(-3) while B[psi(mD) -> Lambda(c)(Lambda) over bar (c)] with m = 6, 7, 8 are of the order of magnitude of 10(-3) - 10(-2). The experimental signals of these missing charmonium states are discussed. The search for them may be an interesting topic in the future BESIII and Belle II experiments.
