Theoretical Development on Pentaquarks

Abstract

I first give a brief overview of the status of exotic hadron search so far. Then I review the recent theoretical development on pentaquarks. Finally I emphasize that none of theoretical formalisms predicts the existence of $\Theta$ pentaquark very reliably. None of them explains its narrow width in a natural way.
