Greetings and Purpose of This Meeting Koshiba Hall 24th November 2005 Physics Department, Graduate School of Science & ICEPP The University of Tokyo Sachio Komamiya Discoveries of Higgs and Supersymmetry to Pioneer Particle Physics of 21st Century MEXT Grand “Higgs and Supersymmetry” On the eve of the 1974 Revolution B.Richter R=σhadrons/σμμ＝ΣQq2 HEP conference １９７４ Summer J.Ellis Leptons Quarks 31 years since the November Revolution Discovery of J/ψ Gauge bosons Higgs boson J/ψ＝ｃｃ bound state e+e- →ψ SLAC Richter et al. J→ e+e- BNL 丁 et al. Leptons Quarks The November Revolution B.Richter ｗith California wine Gauge bosons Higgs boson 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 Gauge bosons Ordinary particles Gauge bosons Higgs bosons Higgs boson SUSY partners Gauginos Scalar Fermions Leptons and Quarks Leptons and Quarks Ordinary particles Dark Matter Candidates Higgsinos Higgs and SUSY are undiscovered Unification of Forces Electricity ？ Electro-magnetic Int. Maxwell Magnetism Electro-Weak Int. Weinberg et al. β -decay Grand-Unification with SUSY Weak Interaction Fermi ＬＥＰ etc. Nuclei Strong Interaction QCD Super-string？ Yukawa ＬＨＣ/ＩＬＣ Terrestrial experiments Galileo Newton Evolution of Planets Kepler Gravity General Relativity Einstein Quantum Gravity？ or Something totally unexpected can be discovered Please enjoy the conference Please come to the party tonight
