RH中微子场耦合到MSSM的模型示出产生一个大参数制度的温暖的通货膨胀。在强耗散制度，它表明，通货膨胀，由一个单一的sneutrino场驱动，发生与所有的场振幅低于普朗克尺度。分析了轻子生成、中微子质量生成和引力子约束。提出了一种新的暖暴胀方案，其中一个标量场驱动一段时间的暖暴胀，第二个标量场驱动随后的再加热阶段。这样的模型能够降低膨胀后的最终温度，从而有助于减轻引力子的限制。
The model of RH neutrino fields coupled to the MSSM is shown to yield a large parameter regime of warm inflation. In the strong dissipative regime, it is shown that inflation, driven by a single sneutrino field, occurs with all field amplitudes below the Planck scale. Analysis is also made of leptogenesis, neutrino mass generation and gravitino constraints. A new warm inflation scenario is purposed in which one scalar field drives a period of warm inflation and a second field drives a subsequent phase of reheating. Such a model is able to reduce the final temperature after inflation, thus helping to mitigate gravitino constraints.
