Linking Starobinsky-type inflation in no-scale supergravity to MSSM
A novel realization of the Starobinsky inflationary model within a moderate extension of the Minimal Supersymmetric Standard Model (MSSM) is presented. The proposed superpotential is uniquely determined by applying a continuous R and a Z2 discrete symmetry, whereas the Kähler potential is associated with a no-scale-type SU(54, 1)/ SU(54)×U(1)R×Z2 Kähler manifold. The inflaton is identified with...
متن کاملStarobinsky ’ s model of inflation : Anomaly - induced inflation , SUSY and graceful exit . 1
We present a model of inflation based on the anomaly-induced effective action of gravity in the presence of a conformally invariant Hilbert-Einstein term. Our approach is based on the conformal representation of the fields action and on the integration of the corresponding conformal anomaly. In contradistinction to the original Starobinsky’s model, inflation can be stable at the beginning and u...

متن کاملDisagreement about Inflation Expectations
Analyzing 50 years of inflation expectations data from several sources, we document substantial disagreement among both consumers and professional economists about expected future inflation. Moreover, this disagreement shows substantial variation through time, moving with inflation, the absolute value of the change in inflation, and relative price variability. We argue that a satisfactory model...
متن کاملStarobinsky-like inflation and neutrino masses in a no-scale SO(10) model
Using a no-scale supergravity framework, we construct an SO(10) model that makes predictions for cosmic microwave background observables similar to those of the Starobinsky model of inflation, and incorporates a double-seesaw model for neutrino masses consistent with oscillation experiments and late-time cosmology. We pay particular attention to the behaviour of the scalar fields during inflati...
