Sneutrino Hybrid Inflation and Nonthermal Leptogenesis
Stefan Antusch, Jochen P. Baumann, Valerie F. Domcke +1
In sneutrino hybrid inflation the superpartner of one of the right-handed neutrinos involved in the seesaw mechanism plays the role of the inflaton field. It obtains its large mass…
Gauge Non-Singlet Inflation in SUSY GUTs
Stefan Antusch, Mar Bastero-Gil, Jochen P. Baumann +3
We explore the novel possibility that the inflaton responsible for cosmological inflation is a gauge non-singlet in supersymmetric (SUSY) Grand Unified Theories (GUTs). For definit…
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…
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…
Solving the -Problem in Hybrid Inflation with Heisenberg Symmetry and Stabilized Modulus
Stefan Antusch, Mar Bastero-Gil, Koushik Dutta +2
We propose a class of models in which the -problem of supersymmetric hybrid inflation is resolved using a Heisenberg symmetry, where the associated modulus field is stabilized a…
