Prospects for Pentaquark Searches in $e^{+}{e}^{-}$ Annihilations and $\gamma \gamma$ Collisions

Abstract

Recent strong experimental evidence of a narrow exotic S = +1 baryon resonance, ${\Theta }^{+}$, suggests the existence of other exotic baryons. We discuss the prospects of confirming earlier experimental evidence of ${\Theta }^{+}$ and the observation of additional hypothetical exotic baryons in $e^{+}{e}^{-}$ annihilations and $\gamma \gamma$ collisions at LEP and B Factories.
