Tribrid Inflation in Supergravity
Stefan Antusch, Koushik Dutta, Philipp M. Kostka
We propose a novel class of F-term hybrid inflation models in supergravity (SUGRA) where the -problem is resolved using either a Heisenberg symmetry or a shift symmetry of the K…
Chaotic Inflation in Supergravity with Heisenberg Symmetry
Stefan Antusch, Mar Bastero-Gil, Koushik Dutta +2
We propose the introduction of a Heisenberg symmetry of the Kahler potential to solve the problems with chaotic inflation in supergravity, as a viable alternative to the use of shi…
SUGRA Hybrid Inflation with Shift Symmetry
Stefan Antusch, Koushik Dutta, Philipp M. Kostka
We propose a solution to the eta-problem in supergravity (SUGRA) hybrid inflation using a Nambu-Goldstone-like shift symmetry within a new class of models. The flatness of the tree…
