Using a high statistics sample of photoproduced charmed particles from the FOCUS experiment at Fermilab (FNAL-E831), we measure the mass splittings of the charmed baryons Σ(c)/0 and Σ(c)/++. We find M(Σ(c)/0 - Λ(c)/+) = 167.38 ± 0.21 ± 0.13 MeV/c2 and M(Σ(c)/++ - Λ(c)/+) = 167.35 ± 0.19 ± 0.12 MeV/c2 with samples of 362 ± 36 and 461 ± 39 events, respectively. We measure the isospin mass splitting M(Σ(c)/++ - Σ(c)/0) to be -0.03 ± 0.28 ± 0.11 MeV/c2. The first errors are statistical and the second are systematic.

Abstract

Using a high statistics sample of photoproduced charmed particles from the FOCUS experiment at Fermilab (FNAL-E831), we measure the mass splittings of the charmed baryons Σ(c)/0 and Σ(c)/++. We find M(Σ(c)/0 - Λ(c)/+) = 167.38 ± 0.21 ± 0.13 MeV/c2 and M(Σ(c)/++ - Λ(c)/+) = 167.35 ± 0.19 ± 0.12 MeV/c2 with samples of 362 ± 36 and 461 ± 39 events, respectively. We measure the isospin mass splitting M(Σ(c)/++ - Σ(c)/0) to be -0.03 ± 0.28 ± 0.11 MeV/c2. The first errors are statistical and the second are systematic.
