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.10 page(s)application/pdfenIn CopyrightMeasurement of the mass and width of the Lambda(c) (2625)(+) charmed baryon and the branching ratios of Lambda(c) (2625)(+)-> Sigma(0)(c)pi(+) and Lambda(c) (2625)(+) -> Sigma(++)(c)pi(-)Article - RefereedPhysical Review Dhttps://doi.org/10.1103/PhysRevD.107.0320081073Piilonen, Leo [0000-0001-6836-0748]2470-0029
