IIB String Theory and Sequestered Inflation

We develop sequestered inflation models, where occurs along flat directions in supergravity models derived from type IIB string theory. It is compactified on a ${\mathbb{T}^6 \over \mathbb{Z}_2 \times \mathbb{Z}_2}$ orientifold with generalized fluxes and O3/O7-planes. At Step I, we use flux potentials which 1) satisfy tadpole cancellation conditions 2) have supersymmetric Minkowski vacua direction(s). The 7 moduli are split into heavy massless Goldstone multiplets. II add nilpotent multiplet uplift the direction(s) of theory to phenomenological inflationary plateau potentials: $\alpha$-attractors discrete values $3\alpha = 1, 2, 3, ..., 7$. Their cosmological predictions determined by hyperbolic geometry inherited masses fields volume extra dimensions change during inflation, but this does not affect dynamics.
