$P$-wave single charmed baryons of the $SU(3)$ flavor ${\bar{3}}_{\mathbf{F}}$

Abstract

We study the $P$-wave single charmed baryons of the $SU(3)$ flavor ${\bar{3}}_{\mathbf{F}}$ 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.
