Skyrmion and chiral symmetry breaking

A chiral coupling is considered for the Skyrme model to a light scalar meson which develops a classical component, eventually representing the scalar quark-anti-quark condensate of the spontaneous breakdown of chiral symmetry. This scalar field leads to a modification in the chiral radius which becomes a dynamical variable and tends to acquire values close to zero inside the topological soliton. A chiral rotation of the scalar and pseudoscalar fields can lead to the linear sigma model favoring the identification of the scalar field to the scalar sigma. The role of the scalar field mass is discussed
