论文摘要
我们检查了在耗散系数的温暖通货膨胀的背景下,检查了铬 - 天然通胀。获得了该模型的动力学方程。我们研究了该模型的宇宙学扰动理论。该模型中密度波动的来源主要是充气场的热波动,例如一般温暖的通货膨胀模型。最后,计算了宇宙学可观察到的光谱指数和张量与标量比。发现宇宙学可观察物与观察数据一致,并且标量比张量小于镀铬自然膨胀中的比率。
We examined the chromo-natural inflation in the context of warm inflation with variable dissipation coefficient. The dynamical equations of this model are obtained. We studied the cosmological perturbation theory in this model. The sources of density fluctuations in this model are mainly the thermal fluctuations of the inflaton field like general warm inflationary model. Finally, cosmological observables, namely, the spectral index and tensor to scalar ratio are calculated. It is found that the cosmological observables are consistent with observational data and the tensor to scalar ratio is smaller than that in the chromo-natural inflation.
