Low-energy effective Lagrangian from nonminimal supergravity with unified gauge symmetry
- Department of Physics, Shinshu University, Matsumoto, 390 (Japan)
From general supergravity theory with unified gauge symmetry, we obtain the low-energy effective Lagrangian by taking the flat limit and integrating out the superheavy fields in a model-independent manner. The scalar potential possesses some excellent features. Some light fields classified by using a supersymmetric fermion mass, in general, would get intermediate masses at the tree level after the supersymmetry is broken. We show that the stability of the weak scale can be guaranteed under some conditions. There exist extra nonuniversal contributions to soft supersymmetry-breaking terms which can give an impact on phenomenological study. {copyright} {ital 1996 The American Physical Society.}
