Soliton states in the quantum-chromodynamic effective Lagrangian
Physical Review D, Particles and fields
The work of Skyrme has shown that the SU(2) &(SU(2) chiral model has nontrivial topological sectors which admit solitons for generic chiral Lagrangians. In this paper, we study such models in the presence of baryon fields. The baryon number and strangeness of the solitons, and the bound states of the nucleon to the soliton are investigated. It is found that long-lived levels with large baryon number B and strangeness ()6 in magnitude) and masses somewhere in the range 1.8 to 5.6 GeV must exist.doi:10.1103/physrevd.27.1153 fatcat:lh4lwly3tjeopp6vtcbsz4kcvq
