We report the observation of the Csi*(c)+ state decaying into Csi(c)0 pi+ with Csi0(c)->Lamda (anti)K0 pi+ pi- or LamdaK−pi+pi+pi−. We have observed 47±11 candidate events for the Csi*(c)+ state and measured its mass to be 177.1±0.5±1.1 MeV/c2 above the Csi(c)0 mass. We have also measured the Csi(c)0 mass to be 2470.0±2.8±2.6 MeV/c2.

Abstract
We report the observation of the Csi*(c)+ state decaying into Csi(c)0 pi+ with Csi0(c)->Lamda (anti)K0 pi+ pi- or LamdaK−pi+pi+pi−. We have observed 47±11 candidate events for the Csi*(c)+ state and measured its mass to be 177.1±0.5±1.1 MeV/c2 above the Csi(c)0 mass. We have also measured the Csi(c)0 mass to be 2470.0±2.8±2.6 MeV/c2.
