Remnants of small-scale dark matter clumps (15'+5')
 
The small-scale dark matter clumps are efficiently disrupted at early stages of
hierarchical structure formation and later in the Galaxy by tidal interactions with
stars. It is demonstrated that a substantial fraction of clump remnants survive
through the tidal destruction during the lifetime of the Galaxy if a clump core
radius is rather small. The resulting mass spectrum of survived clumps is 
extended
down to the core mass of a minimal mass clump. These survived dense 
remnants of
tidally destructed clumps provide a suitable contribution to the amplification
(boosting) of dark matter annihilation signal in the Galaxy.
