abstract = "Using the entire data sample of 980 fb-1 collected at or near the ϒ(4S) resonance with the Belle detector operating at the KEKB asymmetric-energy e+e- collider, we report the measurement of the mass, width, and the branching ratios of the Λc(2625)+ charmed baryon. The mass difference between Λc(2625)+ and Λc+ is measured to be M(Λc(2625)+)-M(Λc+)=341.518±0.006±0.049 MeV/c2. The upper limit on the width is measured to be Γ(Λc(2625)+)<0.52 MeV/c2 at 90% confidence level. Based on a full Dalitz plot fit, branching ratios with respect to the mode Λc(2625)+→Λc+π+π- are measured to be B(Λc(2625)+→ςc0π+)B(Λc(2625)+→Λc+π+π-)=(5.19±0.23±0.40)% and B(Λc(2625)+→ςc++π-)B(Λc(2625)+→Λc+π+π-)=(5.13±0.26±0.32)%, where the first and second uncertainties are statistical and systematic, respectively. These measurements can be used to further constrain the parameters of the underlying theoretical models.",
