引力超对称破缺

Gravitational Supersymmetry Breaking

K. -I. Izawa, T. Kugo, T. T. Yanagida

摘要:

我们考虑超引力中具有纯常数超势的超对称破缺模型。当宇宙学常数为零时,诱导了超对称破缺。作为超对称破缺的一个隐藏中介扇区,它自然会导致超对称标准模型的分裂谱。我们还指出了我们的装置在构造破缺超引力中的非线性西格玛模型和/或Fayet-Iliopoulos类项方面的可能用途。

英文摘要:

We consider supersymmetry breaking models with a purely constant superpotential in supergravity. The supersymmetry breaking is induced for the vanishing cosmological constant. As a hidden mediation sector of supersymmetry breaking, it naturally leads to a split spectrum in supersymmetric standard model. We also point out possible utility of our setup to construct nonlinear sigma model and/or Fayet-Iliopoulos-like term in broken supergravity.
