  Experiments at particle colliders have reached center of mass energies well
above 100 GeV, equivalent to temperatures which existed shortly after the big
bang. These experiments, testing the initial conditions of the universe have,
with great precision, established the Standard Model of Particle Physics. In
contrast, the existence of the Higgs boson and perhaps Supersymmetry remain
speculative, as todays searches have failed to find signs of their existence.
However, the next generation of high energy collider experiments and especially
CERN's 14 TeV LHC, expected to start operation in the year 2005, should lead
either to the discovery of the Higgs and Supersymmetry or disprove todays
theoretical ideas.
