dc.description.abstract | We observe the SIGMA(c)+ baryon decaying to LAMBDA(c)+pi0 and measure the mass difference M(SIGMA(c)+) - M(LAMBDA(c)+) to be 168.5 +/- 0.4 +/- 0.2 MeV/c2. We also measure the mass differences M(SIGMA(c)++) - M(LAMBDA(c)+) and M(SIGMA(c)0) - M(LAMBDA(c)+) with improved precision and determine the isospin mass splittings M(SIGMA(c)++) - M(SIGMA(c)0) and M(SIGMA(c)+) - M(SIGMA(c)0) to be 1.1 +/- 0.4 +/- 0.1 MeV/c2 and 1.4 +/- 0.5 +/- 0.3 MeV/c2, respectively. Our results indicate that the light quark mass difference does not dominate the isospin mass splitting in SIGMA(c). | |
