Query: Propagation of Majorana fermions in hot plasma   The properties of Majorana fermions in hot plasma are studied. One-loop
resummed propagator, dispersion relations and their interpretation are
discussed. It is shown that particle and hole -like solutions appear as in
Dirac/chiral fermion case. The dispersion relations are, however, crucially
different. We find that, in presence of a large zero temperature bare mass,
hole -like excitations posses a negligible effective mass. As an example of
real application, we consider the neutralinos in the minimal supersymmetric
extension of the standard model and argue that for realistic values of the soft
supersymmetry breaking masses the existence of practically massless hole -like
excitations have a considerable effect on the thermal properties, e.g. the
thermalization rate, of particles interacting with these Majorana excitations.
