Measurements of the properties of Λc(2595), Λc(2625), Σc(2455), and Σc(2520) baryons
We report measurements of the resonance properties of Λc(2595)+ and Λc(2625)+ baryons in their decays to Λc+π+π- as well as Σc(2455)++,0 and Σc(2520)++,0 baryons in their decays to Λc+π± final states. These measurements are performed using data corresponding to 5.2 fb-1 of integrated luminosity fro...
