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 workshop is to discuss the theoretical and experimental status of pentaquarks, with the goal of clarifying what can be gained by further experimentation in which channels and at what energy. It will provide guidance for future experimental programs at JLab and elsewhere, if found to be necessary, and give direction to theoretical efforts based upon current experimental knowledge.

Major support for this workshop is from a joint program by Jefferson Lab and the Institute for Nuclear Theory (INT), through grants from the Department of Energy.
