The Search for Exotic Baryons at HERMES

An experimental search for the $\Theta^{+}(1540)$ and $\Xi^{--}(1862) $ resonances was performed using the decay modes $pK_s$ and $\Xi^- \pi^-$, respectively. While evidence for a $\Theta^{+}(1540)$ with a statistical significance of $4\sigma$ is presented, no evidence for the $\Xi^{--}(1862)$ is found. The absence of a peak in the $\Xi^- \pi^-$ spectrum near 1862 MeV allows only to estimate an upper limit for quasi-real photoproduction of the $\Xi^{--}(1862)$. Systematic studies and future plans will be discussed as well. Among those is an attempt to use time-of-flight identification to probe low momentum $\Theta^{+}$ production.
