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.
