Theoretical issues of pentaquarks

Many experiments from around the world have presented evidence for (and against) a possible exotic pentaquark spectrum. Knowledge of the existence, or non-existence, of pentaquark states is of vital importance in the search for the mechanism of quark confinement. "Can four quarks and an antiquark be confined in the same way as three quarks?" is a question of central importance.

The purpose of this talk is to discuss the theoretical and experimental status of pentaquarks.
