论文摘要

在本说明中,我们研究了具有限制超级场地的超级加重模型。我们构建了一个超级框架,其中所有(超级)对称性破坏动态在真空中发生,自然(或其他渐近)消失的能量。超对称性通常在多个扇区中损坏,每个扇区都被尼尔普特·戈德斯蒂诺超级场(Nilpotent Goldstino Superfield)参数化。超对称性量表以下是各种类型的超对称性量表的动态场(Higgs,Aftraton等)。在此框架中,有一个主要的超对称性扇形,可以将潜力提高到零值。超对称破裂的其他来源(渐近)对真空能的贡献消失了,因此局部恢复了超对称性。要求消失的真空能量限制了超电势和卡勒电位的结构。每个僻静的扇区都有一个直接与Nilpotent Superfield相互作用的超电势项,而Kahler势必须沿着希格斯野外方向具有移位对称性。该结构的灵感来自字符串理论中出现的元素。我们还研究了通货膨胀期间的Higgs动力学,并表明在此框架中可以实现Swampland Festina Lente Bounde Bounde。

In this note we study supergravity models with constrained superfields. We construct a supergravity framework in which all (super)symmetry breaking dynamics happen in vacuum with naturally (or otherwise asymptotically) vanishing energy. Supersymmetry is generically broken in multiple sectors each of them is parametrized by a nilpotent goldstino superfield. Dynamical fields (the Higgs, inflaton, etc) below the supersymmetry breaking scale are constrained superfields of various types. In this framework, there is a dominant supersymmetry breaking sector which uplifts the potential to zero value. Other sources of supersymmetry breaking have (asymptotically) vanishing contribution to vacuum energy such that supersymmetry is locally restored. Demanding vanishing vacuum energy constrains the structure of the superpotential and Kahler potential; there is a superpotential term for each secluded sector directly interacting with a nilpotent superfield and the Kahler potential must have a shift symmetry along Higgs field directions. This structure is inspired by elements that appear in string theory. We also study the Higgs dynamics during inflation and show that the swampland Festina Lente bound could be realized in this framework.
