Methods of determining the absolute branching fractions of ${\Lambda }_c^{+}$ baryons and $D_s^{+}$ mesons at hadron colliders

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.
