General dissipative coefficient in warm intermediate and logamediate inflation
arXiv:1310.0780 · doi:10.1103/PhysRevD.88.063535
Abstract
We study a general form for the dissipative coefficient $Î(T,Ï)=C_Ï\,T^{m}/Ï^{m-1}$ in the context of warm intermediate and logamediate inflationary universe models. We analyze these models in the weak and strong dissipative regimes. In the slow-roll approximation, we describe in great detail the characteristics of these models. In both regimes, we use recent data from the WMAP nine-year data and Planck data to constrain the parameters appearing in our models.
