  We have performed three-dimensional molecular dynamics simulation of cohesive
granular particles under a plane shear. From the simulation, we found the
existence of three distinct phases in steady states: (I) a uniform shear phase,
(II) a coexistent phase of a shear band and a gas region and (III) a crystal
phase. We also found that the critical line between (II) and (III) is
approximately represented by $\zeta \propto \exp(\beta \dot\gamma L_y)$, where
$\zeta$, $\beta$, $\dot\gamma$, $L_y$ are the dissipation rate, an unimportant
constant, the shear rate and the system size of the velocity gradient
direction, respectively.
