Abstract

The Lambda(c)(+) baryon mass is measured using Lambda(c)(+)->Lambda (KSK+)-K-0 and Lambda(c)(+)->Sigma(0)K(S)(0)K(+) decays reconstructed in 232 fb(-1) of data collected with the BABAR detector at the PEP-II asymmetric-energy e(+)e(-) storage ring. The Lambda(c)(+) mass is measured to be 2286.46 +/- 0.14 MeV/c(2). The dominant systematic uncertainties arise from the amount of material in the tracking volume and from the magnetic field strength.
