Abstract

We study the P-wave single charmed baryons of the SU(3) flavor \bf3_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 Λ_c(2595), Λ_c(2625), Ξ_c(2790), and Ξ_c(2815), our results suggest the existence of two additional Λ_c baryons and two additional Ξ_c baryons. Their masses, mass splittings within the same multiplets, and decay properties are summarized in Table V for future experimental searches.
