Abstract

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