Abstract
The Λ+c baryon mass is measured using Λ+c→ΛK0SK+ and Λ+c→Σ0K0SK+ decays reconstructed in 232 fb−1 of data collected with the BABAR detector at the PEP-II asymmetric-energy e+e− storage ring. The Λ+c mass is measured to be 2286.46±0.14 MeV/c2. The dominant systematic uncertainties arise from the amount of material in the tracking volume and from the magnetic field strength.
