Abstract
A new resonance, Y(4260) with a mass of 4259 +/- 8(-6)(+2) MeV/c(2) and J(PC) = 1(--), discovered by the BaBar experiment shows peculiar behavior in his decay mode. The Lambda(c)(+) baryon mass has been measured, using its decays to Lambda (KSK+)-K-0 and Sigma(0)K(S)(0)K(+), and its value is 2286.46 +/- 0.14 MeV/c(2), the precision is greatly improved w.r.t. PDG value. E' and Q0 decays and production have been studied with results greatly improved w.r.t. PDG.File in questo prodotto:
