Superheavy neutralinos as dark matter particles (15'+5')

 We propose the lightest supersymmetric particle (LSP) as a well-suited candidate for superheavy dark matter. The mass $m_\chi$ of the LSP should be above $3\times 10^{11}\,{\rm GeV}$, so that gravitational interactions at the end of inflation can produce it with the correct abundance, $\Omega_\chi h^2 \sim 0.1$. Weak interactions remain perturbative despite the large mass hierarchy, $m_\chi\gg m_Z$, because of the special decoupling properties of supersymmetry. As a result the model is predictive and we discuss elastic scattering of neutralinos on light fermions, self-scatterings and briefly annihilations within this scheme.
