What causes mass??The mechanism – Higgs or alternative appears around the corner

Precision measurements at CERN/LEP and

SLAC/SLC establish Standard Model – explains

how particles interact …

But profound

question remain

• Why do the particles all


• Why do the particles all

have different masses,

and where does the mass

come from?
