Two‐Field Axion Inflation and the Swampland Constraint in the Flux‐Scaling Scenario

Based on the flux‐scaling scenario we study a model consisting on Type IIB string theory compactified on a Calabi‐Yau manifold with a frozen complex structure in the presence of generic fluxes. The model contains (meta)stable Minkowski and de Sitter vacua as well as inflationary directions driven by two independent linear combination of axions. Due to a numerical control by fluxes, we show that cosmological parameters as the spectral index,...
