Observation of a new charmed baryon

Description

Using the ARGUS detector at the e+e- storage ring DORIS II at DESY, we have observed a new charmed baryon state in the channel Λc+π+π-1. The mass of this state was measured to be (2626.6±0.5±1.5) MeV/c2. The product of the production cross section and branching ratio for this channel was determined to be (11.5±2.5±3.0) pb, and the natural width estimated to be smaller than 3.2 MeV/c2 at 90% CL.
