✦ Synopsis

An evolution of the density perturbation spectrum of neutralino cold dark matter in an expanding universe is investigated. Background neutralino scattering is taken into account. This scattering is shown to determine the development of the fluctuation spectrum for a long time after neutralino freezing out. A primordial fluctuation spectrum cut-off and the mass of minimal objects are determined.
