Abstract

We present measurements of the masses and decay widths of the baryonic states Σc(2455)0/++ and Σc(2520)0/++ using a data sample corresponding to an integrated luminosity of 711fb-1 collected with the Belle detector at the KEKB e+e- asymmetric-energy collider operating at the (4S) resonance. We report the mass differences with respect to the Λc+ baryon M(Σc(2455)0)-M(Λc+)=167.29±0.01±0.02MeV/c2, M(Σc(2455)++)-M(Λc+)=167.51±0.01±0.02MeV/c2, M(Σc(2520)0)-M(Λc+)=231.98±0.11±0.04MeV/c2, M(Σc(2520)++)-M(Λc+)=231.99±0.10±0.02MeV/c2,and the decay widths Γ(Σc(2455)0)=1.76±0.04-0.21+0.09MeV/c2, Γ(Σc(2455)++)=1.84±0.04-0.20+0.07MeV/c2,Γ(Σ c(2520)0)=15.41±0.41-0.32+0.20MeV/c2,Γ(Σc(2520)++)=14. 77±0.25-0.30+0.18MeV/c2,where the first uncertainties are statistical and the second are systematic. The isospin mass splittings are measured to be M(Σc(2455)++)-M(Σc(2455)0)=0.22±0.01±0.01MeV/c2 and M(Σc(2520)++)-M(Σc(2520)0)=0.01±0.15±0.03MeV/c2. These results are the most precise to date.

N2 - We present measurements of the masses and decay widths of the baryonic states Σc(2455)0/++ and Σc(2520)0/++ using a data sample corresponding to an integrated luminosity of 711fb-1 collected with the Belle detector at the KEKB e+e- asymmetric-energy collider operating at the (4S) resonance. We report the mass differences with respect to the Λc+ baryon M(Σc(2455)0)-M(Λc+)=167.29±0.01±0.02MeV/c2, M(Σc(2455)++)-M(Λc+)=167.51±0.01±0.02MeV/c2, M(Σc(2520)0)-M(Λc+)=231.98±0.11±0.04MeV/c2, M(Σc(2520)++)-M(Λc+)=231.99±0.10±0.02MeV/c2,and the decay widths Γ(Σc(2455)0)=1.76±0.04-0.21+0.09MeV/c2, Γ(Σc(2455)++)=1.84±0.04-0.20+0.07MeV/c2,Γ(Σ c(2520)0)=15.41±0.41-0.32+0.20MeV/c2,Γ(Σc(2520)++)=14. 77±0.25-0.30+0.18MeV/c2,where the first uncertainties are statistical and the second are systematic. The isospin mass splittings are measured to be M(Σc(2455)++)-M(Σc(2455)0)=0.22±0.01±0.01MeV/c2 and M(Σc(2520)++)-M(Σc(2520)0)=0.01±0.15±0.03MeV/c2. These results are the most precise to date.
