The minimal axion minimal linear $$\sigma $$ σ model
Abstract The minimal SO(5) / SO(4) linear $$\sigma $$ σ model is extended including an additional complex scalar field, singlet under the global SO(5) and the Standard Model gauge symmetries. The presence of this scalar field creates the conditions to generate an axion à la KSVZ, providing a solutio...
