Contribution

The paper develops a novel warm vector inflation model using intermediate and logamediate scenarios, aligning it with current observational constraints.

Findings

Model is compatible with WMAP7 and Planck data.

Provides detailed slow-roll and perturbation parameters.

Shows viability of warm vector inflation without reheating.

Abstract

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.
