Generalized inflation in the context of $\kappa$-deformed theories
Abstract
A new inflationary scenario driven by a slowly-rolling homogeneous scalar field whose potential is given by a generalized exponential function is investigated. Within the {\it slow-roll} approximation we obtain the main predictions of the model and compare them with current data from cosmic microwave background and large-scale structure observations. We show that this single scalar field model admits a wider set of solutions than usual exponential scenarios and predicts acceptable values of the spectral index, running of the spectral index and tensor-to-scalar ratio for the remaining number of {\it e}-folds lying in the interval and an energy scale on which ; in particular, we observe that the value of the model parameter depends on the analysis. Finally, the primordial local non-Gaussianity is briefly discussed where we conclude that for .
