A new decay mode of higher charmonium
Abstract We calculate the $$\Lambda _c{\bar{\Lambda }}_c$$ ΛcΛ¯c partial decay width of the excited vector charmonium states around 4.6 GeV with the quark pair creation model. We find that the partial decay width of the $$\Lambda _c{\bar{\Lambda }}_c$$ ΛcΛ¯c mode can reach up to several MeV for $$\p...
