Recent work in supersymmetric astroparticle physics
In the first instants after the big bang the universe was expanding exponentially
due, apparently, to a very great vacuum energy. In less than a second, however, there was a transition to the current mildly inflating universe characterized by
a small but still positive vacuum energy. We have suggested that the ultimate
ground state of the universe will be an exactly supersymmetric state of zero vacuum energy. Recent studies have concentrated on constructing a Lagrangian Higgs model
for this transition 
and on examining the expected properties of this future
supersymmetric universe ,,,.
It has also been suggested that a precursor of this
ultimate vacuum decay may be a susy transition in dense stars , where the
transition probability is strongly enhanced leading to gamma ray bursts. This phase transition
might also serve to trigger the SN Ia explosion in white dwarf stars .
