Аннотация
The spectrum of density perturbations is calculated in the new-inflationary-universe scenario. The main source is the quantum fluctuations of the Higgs field, which lead to fluctuations in the time at which the false vacuum energy is released. The value of $\frac{\ensuremath{\delta}\ensuremath{\rho}}{\ensuremath{\rho}}$ on any given length scale $l$, at the time when the Hubble radius $\ensuremath{\gg}l$, is estimated. This quantity is nearly scale invariant (as desired), but is unfortunately about ${10}^{5}$ times too large.
