Nonperturbative instabilities as a solution of the cosmological moduli problem

Abstract: It is widely accepted that moduli in the mass range 10 eV-10 4 GeV which start to oscillate with an amplitude of the order of the Planck scale either jeopardize successful predictions of nucleosynthesis or overclose the Universe. It is shown that the moduli problem can be relaxed by making use of parametric resonance. A new nonperturbative decay channel for moduli oscillations is discussed. This channel becomes effective when the oscillating field results in a net negative mass term for the decay products. Thi… Show more
