标题： Supermassive gauginos in supergravity inflation with high-scale SUSY breaking

摘要： 我们最近提出的一个超引力暴胀模型可以在没有F项超对称性破缺的情况下产生慢滚暴胀和现实的粒子谱。 仅通过一个最近发现的新类型的Fayet-Iliopoulos (FI) 项引起的D项来破缺超对称性。 几乎所有的标准模型场的超对称伙伴都可以获得高达暴胀哈勃尺度的质量。 例外的是胶子微子，由于F项的消失导致精确抵消，使其质量保持为零。 为了在不破坏我们模型简单性的情况下解决这个问题，我们引入了一个新的项，进一步扩大了超引力有效作用的范围。 这是一个F项，类似于新FI项，在超对称极限下变得奇异。 我们证明这个项可以在不改变其他状态的谱且不降低有效理论截断能标的情况下产生大的胶子微子质量。 显示英文摘要

摘要： A model of supergravity inflation we recently proposed can produce slow roll inflation and a realistic spectrum of particles even without F-term supersymmetry breaking. Supersymmetry is broken only by a D-term induced by a recently discovered new type of Fayet-Iliopoulos (FI) term. Almost all supersymmetric partners of the standard model fields can get masses as high as the inflationary Hubble scale. The exception is gauginos, for which the vanishing of F-terms implies an exact cancellation that keeps their masses exactly zero. To cure this problem without spoiling the simplicity of our model we introduce a new term that further enlarges the space of supergravity effective actions. It is an F-term that, similarly to the new FI term, becomes singular in the supersymmetric limit. We show that this term can produce large gaugino masses without altering the spectrum of other states and without lowering the cutoff of the effecive theory.
