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 Σc++ and Σc0 charmed baryons, and the first measurements of their intrinsic widths. We find M(Σc++)−M(Λc+)=167.4±0.1±0.2 MeV, Γ(Σc++)=2.3±0.2±0.3 MeV, and M(Σc0)−M(Λc+)=167.2±0.1±0.2 MeV, Γ(Σc0)=2.5±0.2±0.3 MeV, where the uncertainties are statistical and systematic, respectively.
CESR'deki CLEO II ve CLEO II.V dedektör konfigürasyonları tarafından kaydedilen verileri kullanarak, Σc++ ve Σc0 tılsımlı baryonlarının kütlelerine ilişkin yeni ölçümleri ve bunların doğal genişliklerinin ilk ölçümlerini bildiriyoruz. Burada belirsizlikler sırasıyla istatistiksel ve sistematik olmak üzere, M(Σc++)−M(Λc+)=167.4±0.1±0.2 MeV, Γ(Σc++)=2.3±0.2±0.3 MeV ve M(Σc0)−M(Λc+)=167.2±0.1±0.2 MeV, Γ(Σc0)=2.5±0.2±0.3 MeV olarak buluyoruz.
