Generalization of the Skyrme model for the unified theory of pions and nucleons
Journal Article

· Phys. Rev. D; (United States)
Skyrme's Lagrangian is generalized within the pion field alone to include all possible terms which appear in the chiral perturbation theory up to fourth order in the field derivative and the symmetry-breaking mass. The parameters entering in the Lagrangian are fixed from the low-energy pion properties. Adding a sixth-order term to the Lagrangian for stabilization the hedgehog soliton is quantized semiclassically. Static properties of the soliton reproduce those of the nucleon with fairly good accuracy.
