Abstract
We investigate brane inflation, focusing on warm inflation realizations within a warped throat geometry. While the standard scenario relies on a single mobile D3-brane moving radially toward an anti- D3-brane at the throat's tip, we propose two distinct single-field inflationary pictures. In our approach, the radial and angular coordinates of a D3-brane on a warped deformed conifold act as two independent inflaton fields. We address moduli stabilization by incorporating a supersymmetrically embedded D7-brane, which generates the necessary radial and angular scalar potentials. Evaluating these radial and angular brane inflation setups within the warm inflation paradigm, we demonstrate that dissipation effects allow the models to satisfy recent observational constraints more naturally than their cold inflation counterparts for a given parameter space.
