Decay properties of $P$-wave charmed baryons from light-cone QCD sum rules

Abstract

We study decay properties of the $P$-wave charmed baryons using the method of light-cone QCD sum rules, including the $S$-wave decays of the flavor ${\bar{3}}_F$ $P$-wave charmed baryons into ground-state charmed baryons accompanied by a pseudoscalar meson ($\pi$ or $K$) or a vector meson ($\rho$ or $K^{\ast }$), and the $S$-wave decays of the flavor $6_F$ $P$-wave charmed baryons into ground-state charmed baryons accompanied by a pseudoscalar meson ($\pi$ or $K$). We study both two-body and three-body decays which are kinematically allowed. We find two mixing solutions from internal $\rho$- and $\lambda$-mode excitations, which can well describe both masses and decay properties of the ${\Lambda }_c(2595)$, ${\Lambda }_c(2625)$, ${\Xi }_c(2790)$ and ${\Xi }_c(2815)$. We also discuss the possible interpretations of $P$-wave charmed baryons for the ${\Sigma }_c(2800)$, ${\Xi }_c(2930)$, ${\Xi }_c(2980)$, and the recently observed ${\Omega }_c(3000)$, ${\Omega }_c(3050)$, ${\Omega }_c(3066)$, ${\Omega }_c(3090)$, and ${\Omega }_c(3119)$.
