Abstract

In this Letter we present a measurement of the natural widths of ∑_c⁰ and ∑_c⁺⁺. Using data from the FOCUS experiment, we find Γ (∑_c⁰) = 1.55_-0.37^+0.41 ± 0.38 MeV/c² and Γ (∑_c⁺⁺) = 2.05_-0.38^+0.41 ±0.38 MeV/c². The first errors are statistical, the second systematic. These results are obtained with a sample of 913 ∑_c⁰ → Λ_c⁺π^- decays and 1110 ∑_c⁺⁺ → Λ_c⁺π⁺ decays. These results are compared with recent theoretical predictions.
