辐射修正在额外维SUSY模型中的作用
The role of radiative corrections on an extradimensional SUSY model
摘要:
具有额外维度坐标的理论提供了实现对称性破裂的有趣机制。在这里,我们提出了一个新的替代通常的几何考虑,以实现超对称破缺的额外维Wess-Zumino模型。构造了一个超对称模型,其中超势包含一个有效的超对称非重整化算子,紧化后,该算子产生了激发态Kaluza-Klein激发的超对称性的显式破缺.超对称破缺又通过辐射修正传递到零模。
英文摘要:
Theories with extra-dimensional coordinates provide interesting mechanisms to achieve the rupture of symmetries. Here we present a novel alternative to the usual geometric considerations to achieve supersymmetric breaking for an extra-dimensional Wess-Zumino model. A supersymmetric model is constructed where the superpotential contains an effective supersymmetric non renormalizable operator, which generates, after compactification, the explicitly rupture of supersymmetry for the excited Kaluza-Klein excitations. The supersymmetry breaking is, in turn, communicated, by the radiatives corrections, to the zero mode.
