Abstract

Current absolute branching fractions of $\Lambda_c^+$ and $D_s^+$ mesons are limiting the determination of important measurements. They have only been measured at $e^+e^-$ colliders. Here techniques for measuring them at hadron colliders are discussed. The precision determination of $\Lambda_c^+\to p K^-\pi^+$ seems possible with current data, however the corresponding determination of $D_s^+\to K^+K^-\pi^+$ will require more integrated luminosity.
