Abstract

The single charmed excited Ξc(2930)\Xi_c(2930) state was discovered many years ago by BABAR collaboration and recently confirmed by Belle experiment. However, both of these experiments, unfortunately, could not fix the quantum numbers of this particle and its nature is under debates. In the present study, we calculate its mass and width of its dominant decay to ΛcK \Lambda_c K . To this end we consider Ξc(2930)\Xi_c(2930) state once as angularly excited and then radially excited single charmed baryon in Ξc \Xi_c channel. Comparison of the obtained results with the experimental data suggests assignment of Ξc(2930)\Xi_c(2930) state as the angular excitation of the ground state Ξc\Xi_c baryon with quantum numbers JP=12J^P=\frac{1}{2}^{-}.
