The gravitino problem in supersymmetric warm inflation

2010/11/16
The warm inflation paradigm considers the continuous production of radiation during inflation
due to dissipative effects. In its strong dissipation limit, warm inflation gives way to a radiation domi...
Galilean symmetry in the effective theory of inflation: new shapes of non-Gaussianity
effective theory of inflation new shapes of non-Gaussianity

We study the consequences of imposing an approximate Galilean symmetry on the Effective Theory
of Inflation, the theory of small perturbations around the inflationary background. This approach allows...
We find the natural embedding of the (R + R2)-inflationary model into the recently constructed
F(R) supergravity. It gives a simple and viable realization of chaotic inflation in supergravity. The on...
Inflation, modulation and baryogenesis with warm directions
warm directions Affleck-Dine warm inflation
2010/3/18
There are many flat directions in SUSY models, which may dissipate their energy
and source the radiation background during inflation. However, the only possibility
that has been studied in this dire...
