广义O 'Raifeartaigh模型的动力学完备化
Dynamical completions of generalized O'Raifeartaigh models
摘要:
本文给出了具有自发破缺R-对称性的超对称破缺真空的Wess-Zumino模型的规范理论完备化。我们的模型是广义ITIY模型的简单变形,广义ITIY模型是一种具有规范群Sp(N)的超对称理论,N+1味加上单态,具有修改的树级超势,它明确地打破了(部分)全局对称性。根据变形的性质,我们得到有效的O 'Raifeartaigh类模型的伪模空间是局部稳定的场空间的原点附近,或在一个区域不包括它。因此,一旦嵌入直接规范调解的情况下,我们的模型可以给出低能量谱,无论是抑制或未抑制的Gaugino质量。
英文摘要:
We present gauge theory completions of Wess-Zumino models admitting supersymmetry breaking vacua with spontaneously broken R-symmetry. Our models are simple deformations of generalized ITIY models, a supersymmetric theory with gauge group Sp(N), N+1 flavors plus singlets, with a modified tree level superpotential which explicitly breaks (part of) the global symmetry. Depending on the nature of the deformation, we obtain effective O'Raifeartaigh-like models whose pseudomoduli space is locally stable in a neighborhood of the origin of field space, or in a region not including it. Hence, once embedded in direct gauge mediation scenarios, our models can give low energy spectra with either suppressed or unsuppressed gaugino mass.
