$P$-wave single charmed baryons of the $SU(3)$ flavor $\bf\bar3_F$

Abstract

We study the $P$-wave single charmed baryons of the $SU(3)$ flavor $\bf\bar3_F$ within the framework of heavy quark effective theory. We systematically calculate their strong and radiative decay properties using the light-cone sum rule method. Besides the $\Lambda_c(2595)$, $\Lambda_c(2625)$, $\Xi_c(2790)$, and $\Xi_c(2815)$, our results suggest the existence of two additional $\Lambda_c$ baryons and two additional $\Xi_c$ baryons. Their masses, mass splittings within the same multiplets, and decay properties are summarized in Table V for future experimental searches.
