Mass Spectra of ${\Lambda }_Q{\bar{\Sigma }}_Q$ Hexaquark States in QCD Sum Rules

Xuan-Heng Zhang, Cong-Feng Qiao

Recently, the BESIII Collaboration indicate that no ${\Lambda }_c{\bar{\Sigma }}_c$ bound-state with a mass near threshold in the range $4715$--$4735\mathrm{MeV}$ was observed. In order to determine…
