Assignments of ${\Lambda }_Q$ and ${\Xi }_Q$ baryons in the heavy quark-light diquark picture

Bing Chen, Ke-Wei Wei, Ailin Zhang

We apply a new mass formula which is derived analytically in the relativistic flux tube model to the mass spectra of ${\Lambda }_Q$ and ${\Xi }_Q$ (\emph{Q} = \emph{c} or \emph{b} quark) baryons…
