Résumé

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 Λ_c⁺π⁺π^-. (All references to a specific charged state also imply the charge conjugate state.) 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.

N2 - 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-. (All references to a specific charged state also imply the charge conjugate state.) 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.
