The Gravitino-Overproduction Problem in Inflaton Decay
We show that the gravitino-overproduction problem is prevalent among inflation models in supergravity. An inflaton field generically acquires (effective) non-vanishing auxiliary field, if the Kähler potential is non-minimal. The inflaton field then decays into a pair of the gravitinos, thereby severely constraining many of the inflation models especially in the case of the gravity-mediated SUSY...
متن کاملInflaton Decay in Supergravity and Gravitino Problem
We have recently shown that, if the inflaton has a nonzero vacuum expectation value, it generically couples to any matter fields that appear in the superpotential at the tree level, and to any gauge sectors through anomalies in the supergravity. Through these processes, the inflaton decays into the supersymmetry breaking sector, producing many gravitinos. The inflaton also directly decays into ...
متن کاملGravitino Overproduction in Inflaton Decay
Most of the inflation models end up with non-vanishing vacuum expectation values of the inflaton fields φ in the true vacuum, which induce, in general, nonvanishing auxiliary field Gφ for the inflaton potential in supergravity. We show that the presence of nonzero Gφ gives rise to inflaton decay into a pair of the gravitinos and are thereby severely constrained by cosmology especially if the gr...
متن کاملOn the Solution to the Polonyi Problem with O(10 TeV) Gravitino Mass in Supergravity
We study the solution to the Polonyi problem where the Polonyi field weighs as O(10TeV) and decays just before the primordial nucleosynthesis. It is shown that in spite of a large entropy production by the Polonyi field decay, one can naturally explain the present value of the baryon-to-entropy ratio, nB/s ∼ (10−10 − 10−11) if the Affleck-Dine mechanism for baryogenesis works. It is pointed out...
متن کاملInflaton Condensate Fragmentation in Hybrid Inflation Models
Inflation ends with the formation of a Bose condensate of inflatons. We show that in hybrid inflation models this condensate is typically unstable with respect to spatial perturbations and can fragment to condensate lumps. The case of Dterm inflation is considered as an example and it is shown that fragmentation occurs if λ ∼ 0.2g, where λ is the superpotential coupling and g is the U(1)FI gaug...
