本文介绍了赝标场与无质量SU（2）规范场直接耦合的温暴胀模型的作用量。在规范场的热浴中，即使暴胀子与光场有很强的直接相互作用，暴胀子的势也不受热修正的影响。该模型的耗散参数是近似恒定的高耗散制度。在这种情况下，该模型与观测数据兼容，并且即使在$f中，非高斯性也是哈勃慢滚参数$\frac{\phi_{\phi}}{1+Q}$的顺序
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
