Sequestered inflation in M-theory and string theory

We build supergravity models which sequester phenomenology of inflation from the Planck scale physics. The construction involves the nilpotent chiral multiplet representing non-linearly realized supersymmetry and an anti-D3 brane. We use novel type flux superpotentials originating from M-theory and type IIB string theory and the associated Goldstone multiplets. Our construction explains the origin of inflationary plateau potentials favored by the current BICEP/Keck and Planck data and provides the B-mode targets for future CMB experiments.
