最近，[1]中提出了一种新的暴胀场景，它可以适用于具有多个真空的暴胀子。在这封信中，我们考虑了一种更一般的情况，其中暴胀势在普朗克尺度附近有一个（紫外线）鞍点。这类模型可以被视为爬山希格斯暴胀的自然推广[2]。
Recently a new inflationary scenario was proposed in [1] which can be applicable to an inflaton having multiple vacua. In this letter, we consider a more general situation where the inflaton potential has a (UV) saddle point around the Planck scale. This class of models can be regarded as a natural generalization of the hillclimbing Higgs inflation [2].
