Description

The Θ+ Pentaquark is a Very narrow Λ ∼ 1 MeV KN Resonance. Why do some experiments see it and others do not? The lowest quark configuration that can describe it is exotic uudd(bar s). Why have no exotics been seen before? Is this the beginning of a new spectroscopy? Can it help to teach us about How QCD makes hadrons from quarks and gluons?
