Symmetry Breaking Indication for Supergravity Inflation in Light of the Planck 2015
Tianjun Li, Zhijin Li, Dimitri V. Nanopoulos
The supergravity (SUGRA) theories with exact global symmetry or shift symmetry in Kähler potential provide the natural frameworks for inflation. However, the quadratic infla…
Supergravity Inflation with Broken Shift Symmetry and Large Tensor-to-Scalar Ratio
Tianjun Li, Zhijin Li, Dimitri V. Nanopoulos
We propose a class of inflation models with potential V(ϕ)=αϕ^n exp(-β^m ϕ^m). We show that such kind of inflaton potentials can be realized in supergravity theory with a small shi…
No-Scale Ripple Inflation Revisited
Tianjun Li, Zhijin Li, Dimitri V. Nanopoulos
We revisit the no-scale ripple inflation model, where no-scale supergravity is modified by an additional term for the inflaton field in the Kahler potential. This term not only bre…
