Measurement of the $\Lambda_c$ Mass

We present a precision measurement of the mass of the $\Lambda_c^+$ baryon using data collected by the BaBar experiment. To keep the systematic uncertainty as low as possible, the measurement is done using the low Q-value decay, $\Lambda_c^+ \to \Lambda^0 K_S^0 K^+$. The measurement requires a thorough understanding of the tracking performance and energy loss corrections which is demonstrated using several control samples.
