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.
