我们考虑最小尺度不变扩展的标准模型，允许成功的辐射电弱对称性破缺和通货膨胀。该框架涉及一个额外的标量单线态，它扮演着暴胀子的角色，并且由于后者与引力的非最小耦合而与当前的实验边界兼容。这种暴胀的情形预言了一个非常低的张量-标量比r <$10 −3，这是希格斯暴胀模型的典型特征，但与此相反，它产生了一个偏离斯塔罗宾斯基极限的标量谱指数ns <$0.97。我们简要讨论了框架的对撞机现象学。
We consider the most minimal scale invariant extension of the standard model that allows for successful radiative electroweak symmetry breaking and inflation. The framework involves an extra scalar singlet, that plays the rôle of the inflaton, and is compatibile with current experimental bounds owing to the non-minimal coupling of the latter to gravity. This inflationary scenario predicts a very low tensor-to-scalar ratio r ≈ 10−3, typical of Higgs-inflation models, but in contrast yields a scalar spectral index ns ≃ 0.97 which departs from the Starobinsky limit. We briefly discuss the collider phenomenology of the framework.
