Strong decay properties of single heavy baryons $\hat{I}{›}_Q$, $\hat{I}{\pounds }_Q$ and $\hat{I}{\text{c◯}}_Q$

Abstract

Motivated by recent progresses in experiments in searching for the $\hat{I}{\text{c◯}}_c$ baryons, we systematically analyze the strong decay behaviors of single heavy baryons $\hat{I}{›}_Q$, $\hat{I}{\pounds }_Q$ and $\hat{I}{\text{c◯}}_Q$. The two-body strong decay properties of $S$-wave, $P$-wave and some $D$-wave states are studied with the ${}^3{P}_0$ model. The results support assigning the recently observed $\hat{I}{\text{c◯}}_c(3185)$ and $\hat{I}{\text{c◯}}_c(3327)$ as the 2S(${\frac{3}{2}}^{+}$) and 1D(${\frac{3}{2}}^{+}$) states, respectively. In addition, the quantum numbers of many other experimentally observed baryons are also suggested according to their strong decays. Finally, some baryons which have good potentials to be observed in experiments are predicted and the possible decay channels for searching for these predicted states are also suggested.
