Abstract:
In recent years the possibility of indirect
detection of WIMPs (Weak Interacting Massive Particles) by observing
their final decay or annihilation by-products (gamma-rays, neutrinos,
positrons) has been discussed in detail. In particular it has been
pointed out as a possible detection method the observation of the
synchrotron emission produced by high energy electrons and positrons
propagating in the Galactic or in the halo magnetic field. I outline
here a short resume of the activity carried out at the OAT in the
framework of the Planck mission. The conditions in which synchrotron
emission from WIMPs annihilation in DM clumps may be detected in
Planck are analysed, taking into account the DM distribution profile
in clumps, the possible range of neutralino masses and cross sections,
the annihilation channels and the magnetic field.
