Search for pentaquark with $\gamma $, $\pi ^{-}$ and K$^{+}$ beams

Several experiments to search for the pentaquark, $\Theta ^{+}$, have been made with $\gamma $, $\pi ^{-}$ and K$^{+}$ beams at SPring8 and KEK-PS. It is important to observe the signal with both $\gamma $ and hadron beams at low energies for the confirmation of $\Theta ^{+}$. The KEK-E522 has searched for $\Theta ^{+}$ through $\pi ^{-}$+p -$>$ K$^{-}+\Theta ^{+}$ reaction. The KEK-E559 searches for $\Theta ^{+}$ through K+p -$>\pi ^{+}+\Theta ^{+}$ reaction with mass resolution of 1.3MeV(FWHM). Some results and status of thsese experiments are presented as well as those from SPring8.
