Global U(1) Invariance and Mass Scales in Supersymmetry
arXiv:hep-ph/0104089 · doi:10.1088/0954-3899/27/12/304
Abstract
In a supersymmetric theory with global U(1) invariance, the spontaneous breaking of the latter without the breaking of supersymmetry is revisited in the case of the most general superpotential of 3 singlet superfields. The interesting possibility of having 2 hierarchical mass scales is pointed out, together with its consequences as applied to the axionic solution of the strong CP problem.
