摘要：
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 Sigma(c)(0) and Sigma(c)(++). We find M(Sigma(c)(0) - Lambda(c)) = 167.38 +/- 0.21 +/- 0.13 MeV/c(2) and M(Sigma(c)(++) - Lambda(c)(+)) = 167.35 +/- 0.19 +/- 0.12 MeV/c(2) with samples of 362 +/- 36 and 461 +/- 39 events, respectively. We measure the isospin mass splitting M(Sigma(c)(++) - Sigma(c)(0)) to be -0.03 +/- 0.28 +/- 0.11 MeV/c(2). The first errors are statistical and the second are systematic.
