标题： Warm (Pseudo)Scalar Inflation

摘要： 在本文中，我们将介绍一种温胀模型的作用量，该模型具有赝标量场与无质量的$SU(2)$规范场之间的直接耦合。 即使膨胀子与轻场之间存在强直接相互作用，在规范场的热浴中，膨胀子的势能也能免受热修正的影响。 在这个模型中，耗散参数在高耗散区域近似为常数。 在此区域内，该模型与观测数据兼容，并且非高斯性与哈勃慢滚参数$\frac{\epsilon_{\phi}}{1+Q}$同阶，甚至在$f<M_p$极限下也是如此。 显示英文摘要

摘要： In this note, we will introduce an action for warm inflation model with direct coupling between the pseudoscalar field and mass-less $SU(2)$ gauge fields. The potential of inflaton is protected against the thermal corrections in a thermal bath of gauge fields even with strong direct interaction between inflaton and light fields. The dissipation parameter of this model is approximately constant in the high-dissipative regime. In this regime, the model is compatible with observational data and non-Gaussianity is in order of Hubble slow-roll parameter $\frac{\epsilon_{\phi}}{1+Q}$ even in $f<M_p$ limit.
