On the realization of the MSSM inflation
We study the fine-tuning problem on the initial condition of inflation in the minimal supersymmetric standard model (MSSM), associated with the narrowness of the slow-roll region. We consider two cases before the onset of the MSSM inflation, namely, the radiation dominated era and preceding inflationary era. We find thermal dissipation does not induce additional friction to the inflaton, so tha...
متن کاملWarm Inflation Dissipative Dynamics
Warm inflation dynamics is reviewed. Results on dissipative scalar field dynamics relevant to warm inflation are examined and estimates of radiation production are given.
متن کاملDissipative Dynamics of Inflation
Dissipative scalar quantum field theory is examined at zero temperature. Estimates of radiation production are given. Relevance of the results to supercooled and warm inflation are discussed. To appear in Proceeding, PASCOS-01, 2001 The basic picture of inflationary dynamics centers around a scalar field often called the inflaton. During the inflationary period, the potential energy of this fie...
متن کاملRemote Inflation as hybrid-like sneutrino/MSSM inflation
A new scenario of hybrid-like inflation is considered for sneutrino and MSSM fields. Contrary to the usual hybrid inflation model, the direct coupling between a trigger field and the sneutrino/MSSM inflaton field is not necessary for the scenario. The dissipation and the radiation from the sneutrino/MSSM inflaton can be written explicitly by using the Yukawa couplings. Remote inflation does not...
متن کاملA-term inflation and the MSSM
The parameter space for A-term inflation is explored with W = λpφ p/pM P . With p = 6 and λp ∼ 1, the observed spectrum and spectral tilt can be obtained with soft mass of order 10 GeV but not with a much higher mass. The case p = 3 requires λp ∼ 10 to 10. The ratio m/A requires fine-tuning, which may be justified on environmental grounds. An extension of the MSSM to include non-renormalizable ...
