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 → Λc+π- decays and 1110 ∑c++ → Λc+π+ decays. These results are compared with recent theoretical predictions.

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 → Λc+π- decays and 1110 ∑c++ → Λc+π+ decays. These results are compared with recent theoretical predictions.
