Dark Radiation predictions from general Large Volume Scenarios

  title={Dark Radiation predictions from general Large Volume Scenarios},
  author={Arthur Hebecker and P Daisy Mangat and Fabrizio Rompineve and Lukas T. Witkowski},
Recent observations constrain the amount of Dark Radiation (∆Neff) and may even hint towards a non-zero value of ∆Neff . It is by now well-known that this puts stringent constraints on the sequestered Large Volume Scenario (LVS), i.e. on LVS realisations with the Standard Model at a singularity. We go beyond this setting by considering LVS models where SM fields are realised on 7-branes in the geometric regime. As we argue, this naturally goes together with high-scale supersymmetry.
