Preheating in Supersymmetric Theories
We examine the particle production via preheating at the end of inflation in supersymmetric theories. The inflaton and matter scalars are now necessarily complex fields, and their relevant interactions are restricted by holomorphy. In general this leads to major changes both in the inflaton dynamics and in the efficiency of the preheating process. In addition, supersymmetric models generically ...
متن کاملPreheating in Supersymmetric Hybrid Inflation
We study preheating in a general class of supersymmetric hybrid inflation model. Supersymmetry leads to only one coupling constant in the potential and thus only one natural frequency of oscillation for the homogeneous fields, whose classical evolution consequently differs from that of a general (non-supersymmetric) hybrid model. We emphasise the importance of mixing effects in these models whi...
متن کاملPreheating in Generalized Einstein Theories
One of the most important epochs in the history of inflationary Universe is the transition from almost De Sitter expansion to the radiation dominated universe. Until few years ago proper understanding of this phenomena was not well established. Recent development in the theory of resonant particle creation of bosons [1] as well as fermions [2] due to coherent oscillations of the Bose-condensate...
متن کاملPhase transitions from preheating in gauge theories
We show by studying the Abelian Higgs model with numerical lattice simulations that nonthermal phase transitions arising out of preheating after inflation are possible in gauge-Higgs models under rather general circumstances. This may lead to the formation of gauged topological defects and, if the scale at which inflation ends is low enough, to electroweak baryogenesis after preheating.
متن کاملPreheating and Phase Transitions in Gauge Theories
It has recently been suggested that the baryon washout problem of the standard electroweak baryogenesis scenario could be avoided if inflation ends with a period of parametric resonance at a low enough energy density. I present results of numerical simulations in which this process was studied in the Abelian Higgs model. Our results show that because of the masslessness of the gauge field, the ...
