Kaon-soliton bound state approach to the pentaquark states

Abstract

We show that in hidden local symmetry theory with the vector manifestation (VM), a K+ can be bound to skyrmion to give an exotic baryon that has the quantum numbers of the Θ+ pentaquark with spin 1/2 and even parity which is consistent with large Nc counting. The vector meson K* subject to the VM in the chiral limit plays an essential role in inducing the binding.
