dc.descriptionThe problem of the long life time of the pentaquark $Θ^+$ is investigated on the basis of the color molecular dynamics simulation. We find that it takes a long time (typically of 50-100 fm/c) for the initial pentaquark-state to rearrange its color and spatial positions to decay into the nucleon + kaon final state. Structure of the potential surface in the color and position spaces also supports this picture. Pentaquark wanders on the potential surface to find a narrow channel to decay.
