elementary particle physics (EPP)
is investigating fundamental questions about the structure
and behaviour of the universe. Our work provides
information about the weak and strong forces
(counterparts to gravity and electromagnetism) and
offers sensitive probes for new fundamental phenomena.
There is growing evidence that discoveries in the next decade may
bring to light new physical phenomena that will shed light on
important mysteries. For example, the matter
asymmetry of the universe tells us two things: there must be large
sources of CP violation we have not yet found and there must be baryon
number violating processes, which are also not yet observed. Also,
the amount of dark matter in the universe is about ten times larger
than the amount of baryonic matter, but no dark matter candidates have
been observed. An unknown force, often called ``dark energy,''
is forcing the universe apart. These are only three examples.
