Measurement of the masses and widths of the c++ and c0 charmed baryons Academic Article uri icon

abstract

  • Using data recorded by the CLEO II and CLEO II.V detector configurations at CESR, we report new measurements of the masses of the c++ and c0 charmed baryons, and the first measurements of their intrinsic widths. We find M(c++)-M(c+) =167.40.10.2 MeV, (c++)=2.30.20.3 MeV, and M(c0) -M(c+)=167.20.10.2 MeV, (c0)=2.50.20.3 MeV, where the uncertainties are statistical and systematic, respectively.
