The authors' main claim The motion of the D3-brane towards D7 in a phase with spontaneously broken supersymmetry provides a period of slow-roll inflation in the de Sitter valley, the role of the inflaton being played by the distance between D3 and D7-branes.

A proposal is made for a cosmological D3/D7 model with a constant magnetic flux along the D7 world-volume. It describes an N=2 gauge model with Fayet-Iliopoulos terms and the potential of the hybrid P-term inflation. The motion of the D3-brane towards D7 in a phase with spontaneously broken supersymmetry provides a period of slow-roll inflation in the de Sitter valley, the role of the inflaton being played by the distance between D3 and D7-branes. After tachyon condensation a supersymmetric ground state is formed: a D3/D7 bound state corresponding to an Abelian non-linear (non-commutative) instanton. In this model the existence of a non-vanishing cosmological constant is associated with the resolution of the instanton singularity. We discuss a possible embedding of this model into a compactified M-theory setup.

The paper

Original abstract

A proposal is made for a cosmological D3/D7 model with a constant magnetic flux along the D7 world-volume. It describes an N=2 gauge model with Fayet-Iliopoulos terms and the potential of the hybrid P-term inflation. The motion of the D3-brane towards D7 in a phase with spontaneously broken supersymmetry provides a period of slow-roll inflation in the de Sitter valley, the role of the inflaton being played by the distance between D3 and D7-branes. After tachyon condensation a supersymmetric ground state is formed: a D3/D7 bound state corresponding to an Abelian non-linear (non-commutative) instanton. In this model the existence of a non-vanishing cosmological constant is associated with the resolution of the instanton singularity. We discuss a possible embedding of this model into a compactified M-theory setup.

de Sitter Vacua in String Theory
hep-th 2003-01 conditional novelty 9.0 of 10

Type IIB flux compactification, plus a non-perturbative superpotential, plus a warped anti-D3 uplift, yields a metastable de Sitter vacuum with all moduli fixed and a lifetime far exceeding 10^10 years.
Towards Inflation in String Theory
hep-th 2003-08 accept novelty 8.0 of 10

A warped throat produces a flat brane-antibrane inflaton potential, but superpotential stabilization of the compactification volume generically gives the inflaton m^2 = 2H^2 and ends slow roll.

The paper derives a corrected Type IIB D7-brane superpotential, shows the extended no-scale cancellation survives a light brane modulus, and argues fluxbrane inflation can be made parametrically consistent, though onl...
D7-Brane Chaotic Inflation

D7-brane position moduli in Type IIB orientifolds can serve as large-field inflatons, with a mirror-symmetry shift symmetry and flux-induced monodromy, provided the flux coefficients can be tuned small.

Open-string one-loop corrections to D-brane gauge kinetic functions restore holomorphy in the brane-modified volume modulus and introduce explicit inflaton dependence in the gaugino-condensation superpotential, offeri...

Cosmological data allow localized bump-like features in the primordial power spectrum as large as 10% of the scale-invariant fluctuations, bounding the inflaton-iso-inflaton coupling to roughly g^2 < 0.01 on CMB scales.

hep-th 2013-06 conditional novelty 3.0 of 10

A survey of string-inflation models finds that their pre-Planck predictions mostly sit near the observed spectral index with very small tensor-to-scalar ratio, so future tensor detection would rule out most of them.

The second, D3/D7 inflation [ref] , has serious issues which we aim to overcome: In D3/D7 inflation, supersymmetry is broken by non-selfdual flux on the D7-brane.

While our scenario is conceptually similar to D3/D7 inflation [ref] , it has significant advantages concerning the field range of the inflaton: The fact that a D7- rather than a D3-brane moves in the compact space enhances the relevant kinetic term.
