We are now on the eve of
the next Revolution
ATLAS Experiment
MEG Experiment
Theoretical Studies
towards construction of ILC
Higgs Boson
All the interactions are governed by
the sacred Gauge Symmetry
Higgs Boson breaks the Gauge
Symmetry and gives mass to all
the elementary particles.
LEP experiments chased Higgs
into a small corner of the
parameter space: 114~200 GeV
The last particle in the Standard
Model
The most urgent subject in particle
physics
Direct Discovery of Higgs Boson
Supersymmetry (SUSY)
・SUSY is a space-time symmetry
It plays a crucial role for the unification of forces with gravity
・ Every Elementary Particle has SUSY partner, mass of them ≦ TeV
⇒ The value of the discovery is that for the Anti-particle
・ The lightest SUSY particle is the best candidate of the Dark Matter
⇒ Understanding of the structure of the universe
