Abstract
We investigate the decay modes of pentaquark baryons for both the antidecuplet and the octet states, which were recently claimed by Close and Dudek to be potentially narrow due to a hidden selection rule. We discuss how ideal mixing between the pentaquark octet and antidecuplet states can be related to the OZI rule, which also naturally leads to certain selection rules in the pentaquark decays. We then introduce a tensor representation for the pentaquark states and present possible decay modes for both the unmixed and the ideally mixed pentaquark octet and antidecuplet states. The exclusive decay modes can be used to experimentally search for other pentaquark states.
