A Precision Measurement of the Lambda_c Baryon Mass

B. Aubert, The BABAR Collaboration

The ${\Lambda }_c^{+}$ baryon mass is measured using ${\Lambda }_c^{+}\to \Lambda K_S^0{K}^{+}$ and ${\Lambda }_c^{+}\to {\Sigma }^0{K}_S^0{K}^{+}$ decays reconstructed in 232 fb${}^{-1}$ of data collected with the BaBar detector at the PE…
