abstract
Since LEPS collaboration reported the first evidence of = H
pentaquark in early 2003,
eleven other experimental groups have confirmed this exotic
state while many other
groups didn’t see any signal. If this state is further
established by future high statistical
experiments, its discovery shall be one of the most important
events in hadron
physics for the past three decades. This exotic baryon with such
a low mass and so
narrow a width imposes a big challenge to hadron theorists. Up
to now, there have
appeared more than two hundred theoretical papers trying to
interpret this charming
state. I will review some important theoretical developments on
pentaquarks.
