The Beam-Helicity Asymmetries for the Reactions $\gamma p \rightarrow p K^{+} K^{-}$, $\gamma p \rightarrow \Xi^{-} K^{+} K^{+}$, and $\gamma p \rightarrow p \pi^{+} \pi^{-}$

The first time measurement of the angular dependence of the beam-helicity asymmetry is demonstrated for the reactions $\gamma p \rightarrow p K^{+} K^{-}$ and $\gamma p \rightarrow \Xi^{-} K^{+} K^{+}$. Both results are compared to the beam-helicity asymmetry of the reaction $\gamma p \rightarrow p \pi^{+} \pi^{-}$. The asymmetry for $\gamma p \rightarrow p K^{+} K^{-}$ is further studied as a function of the kinematical variables photon beam energy, invariant mass of the $K^{+} K^{-}$ system, and invariant mass of the $p K^{-}$ system. It is shown that the asymmetry is sensitive to these variables and thus are key observables in the modeling of the reaction's dynamics. The data obtained was from the CLAS g12 experiment.
