A new resonance Y(4260) with a mass of 4259 {+-} 8{sub -6}{sup +2} MeV/c{sup 2} and J{sup PC} = 1{sup --}, discovered by the BaBar experiment shows peculiar behavior in his decay mode. The {Lambda}{sub c}{sup +} baryon mass has been measured, using its decays to {Lambda}K{sub S}{sup 0} K{sup +} and {Sigma}{sup 0}K{sub S}{sup 0}K{sup +}, and its value is 2286.46 {+-} 0.14 MeV/c{sup 2}, the precision is greatly improved w.r.t. PDG value. {Xi}{sub c}{sup 0} and {Omega}{sub c}{sup 0} decays and production have been studied with results greatly improved w.r.t. PDG.
