暖向量膨胀

Warm Vector Inflation

M. R. Setare, V. Kamali

摘要:

在本文中,我们介绍了“温暖的矢量通货膨胀”的情况。在暖暴胀的情况下,辐射是在暴胀时期产生的,并且避免了再加热。给出了该模型的慢滚参数和扰动参数。我们使用中间通货膨胀模型发展我们的模型。在这种情况下,该模型与观测数据兼容。我们还研究了模型使用另一种精确的宇宙学解决方案,命名为logmediate方案。我们提出慢滚和哈勃参数,功率谱和张量标量比的暴胀。该模式与WMAP7和普朗克观测数据兼容。

英文摘要:

In this paper we introduce the "warm vector inflation" scenario. In warm inflation scenario radiation is produced during the inflation epoch and reheating is avoided. Slow-roll and perturbation parameters of this model are presented. We develop our model using intermediate inflation model. In this case, the model is compatible with observational data. We also study the model using another exact cosmological solution, named logamediate scenario. We present slow-roll and Hubble parameters, power spectrum and tensor-scalar ratio in terms of inflaton. The model is compatible with WMAP7 and Planck observational data.
