Radial Excitations of low-lying Baryons and the Structure of the Z+ Penta-QuarK
Herbert Weigel
Abstract
Within the collective quantization scheme for chiral solitons we discuss states in higher dimensional representations of flavor SU(3) and their relation to radially excited states in the octet. We also consider states which do not have counterparts of the same quantum numbers in the octet or decuplet and cannot be built from three quarks. We focus on the Z+ penta-quark, presumably the lightest such state, by estimating its mass and decay width.
