摘要：

The possibility of amplification of the annihilation signal from dark matter in the Galaxy halo due to its clusterization into small-mass clumps (about the Moon’s or Earth’s mass) is discussed. Formation of dark-matter clumps is considered within the conventional cosmological model taking into account their hierarchical clustering and tidal destruction. It is shown that the amplification factor of γ rays from dark-matter annihilation due to small-mass clumps in the Galaxy may range from 10 to 1000.
