Strangeness in the Skyrme and in Nambu-Jona Lasinio Models
Abstract
We discuss the phenomenology of SU(3) Skyrme and Nambu--Jona-Lasinio models. We show that while the Skyrme model, in its simplest version, is unable do reproduce the hyperon spectrum, the NJL model describes both hyperon and isospin splittings with satisfactory accuracy. The difference between the two models lies in new anomalous moments of inertia, which vanish in the Skyrme model and get non-zero contribution from the valence quarks in the NJL model
