Photoproduction and radiative decay of spin 1/2 and 3/2 pentaquarks

We study photoproduction and radiative decays of pentaquarks paying particular attention to the differences between spin-1/2 and spin-3/2, positive and negative parities of pentaquarks. Detailed study of these processes can not only give crucial information about the spin, but also the parity of pentaquarks.
