The present description of matter - the Standard Model of particles and forces is being tested at LEP to great precision and proving remarkably successful. This is all the more surprising because the origin of one of the most fundamental properties of matter - mass - remains unknown. We do not know yet whether particles really do gain their different masses through the Higgs mechanism. |
In addition there are important questions that the Standard Model cannot answer. Can the
electroweak and the strong forces be unified? Why are there six kinds of quark? Do
neutrinos have mass? Such questions also relate to current mysteries about the Universe.
Is there more to the Universe than meets the eye? Why does matter dominate antimatter?
With all these questions in mind, CERN is preparing for the 21st century by building a new
machine, the Large Hadron Collider, or LHC, which will reach higher energies than ever
before.
