Higgs-otic Inflation and Moduli Stabilization
Sjoerd Bielleman, Luis E. Ibanez, Francisco G. Pedro +2
We study closed-string moduli stabilization in Higgs-otic inflation in Type IIB orientifold backgrounds with fluxes. In this setup large-field inflation is driven by the vacuum ene…
Challenges for D-brane large-field inflation with stabilizer fields
Aitor Landete, Fernando Marchesano, Clemens Wieck
We study possible string theory compactifications which, in the low-energy limit, describe chaotic inflation with a stabilizer field. We first analyze type IIA setups where the inf…
The DBI Action, Higher-derivative Supergravity, and Flattening Inflaton Potentials
Sjoerd Bielleman, Luis E. Ibanez, Francisco G. Pedro +2
In string theory compactifications it is common to find an effective Lagrangian for the scalar fields with a non-canonical kinetic term. We study the effective action of the scalar…
UV Corrections in Sgoldstino-less Inflation
Emilian Dudas, Lucien Heurtier, Clemens Wieck +1
We study the embedding of inflation with nilpotent multiplets in supergravity, in particular the decoupling of the sgoldstino scalar field. Instead of being imposed by hand, the ni…
