Decays of Roper-like singly heavy baryons in a chiral model

We present a chiral model describing decays of the Roper-like ${\mathrm{\ensuremath{\Lambda}}}_{c}(2765)$ and ${\mathrm{\ensuremath{\Xi}}}_{c}(2970)$ as well those heavy quark spin-doublet ${{\mathrm{\ensuremath{\Sigma}}}_{c}(2455),{\mathrm{\ensuremath{\Sigma}}}_{c}(2520)}$ ${{\mathrm{\ensuremath{\Xi}}}_{c}^{\ensuremath{'}},{\mathrm{\ensuremath{\Xi}}}_{c}(2645)}$, by focusing on representations diquarks inside baryons. Based our together with spin symmetry, we derive relation satisfied axial charges baryons that controls magnitude their one pion (kaon) decays. Besides, it is shown large decay widths ${\mathrm{\ensuremath{\Xi}}}_{c}(2970)$, which cannot be implemented conventional nonrelativistic models, are explained reasonable values charges. In addition, apply to bottom predict undiscovered ${\mathrm{\ensuremath{\Xi}}}_{b}$. expect investigation leads elucidation dynamical properties excited from viewpoint symmetry.
