摘要： 一种振荡的暴胀场在暴胀结束时会诱导哈勃参数的小幅度振荡。这些由哈勃参数诱导的振荡反过来会触发所有轻场的参数化粒子产生，即使它们没有直接与暴胀场耦合。我们在此研究了由于这种效应，在暴胀之后一个轻标量场（例如标准模型的希格斯场）引起的粒子产生的诱导效应。我们的分析给出了从暴胀凝聚态到粒子激发的能量转移效率的一个模型无关的下限。 显示英文摘要

摘要： An oscillating inflaton field induces small amplitude oscillations of the Hubble parameter at the end of inflation. These Hubble parameter induced oscillations, in turn, trigger parametric particle production of all light fields, even if they are not directly coupled to the inflaton. We here study the induced particle production for a light scalar field (e.g. the Standard Model Higgs field) after inflation as a consequence of this effect. Our analysis yields a model-independent lower bound on the efficiency of energy transfer from the inflaton condensate to particle excitations.
