We reanalyze brane inflation with brane-brane interactions at an angle, which include the special case of brane-anti-brane interaction. If nature is described by a stringy realization of the brane world scenario today (with arbitrary compactification), and if some additional branes were present in the early universe, we find that an inflationary epoch is generically quite natural, ending with a big bang when the last branes collide. In an interesting brane inflationary scenario suggested by generic string model-building, we use the density perturbation observed in the cosmic microwave background and the coupling unification to find that the string scale is comparable to the GUT scale.

  1. Production of Primordial Black Holes in the Double D3-Brane - anti-D3-Brane Inflation Model

    hep-th 2026-08 reject novelty 6.0 of 10

    In a double D3-anti-D3 brane inflation model, Myers dielectric effect may turn D1-strings into neutral 3-branes seeding primordial black holes, but the mass distribution is not derived.

    Inflation from a UV-brane inflaton in a warped 5D bulk with an IR brane predicts a blue-tilted low-k scalar spectrum and oscillating tensor features because the early adiabatic modes come from the radion.
