  1. 6元模型誕生をめぐって 小林　誠

  2. C, P, T • P parity Wigner 1928 • T time reversal Wigner 1932 • C charge conjugation Krammers 1937 CPT theorem 1954~

  3. P Violation θ-τPuzzle Lee-Yang　（１９５６）　 Wu　（１９５７） V-A theory

  4. x CP Violation CP eigenstates Gell-Mann Pais 1955 Christenson, Cronin, Fitch, Turlay (1964)

  5. 1953Nakano, Nishijima, Gell-Mann 1956 Sakata Sakata model 1959 Gamba, Marshak, Okubo 1960 Maki, Nakagawa, Ohnuki, Sakata Nagoya model

  6. Discovery of two neutrinos 1962Danby etal. 1962Maki, Nakagawa, Sakata 1962Katayama, Matumoto, Tanaka, Yamada

  7. 1971 Niu et al.

  8. 大学院時代　（１９６７－１９７２） Chiral Dynamics/Chiral Symmetry クォーク模型の視点から理解する 自発的対称性の破れetc ４元模型 全体像を描くことを目指す

  9. ～1971　電・弱相互作用が繰り込み可能 　　　　　　（Weinberg-Salam-Glashow, ‘ｔ Hpoft）　　 CPの破れをどう繰り込み可能な枠組みで記述するか 1973 Kobayashi, Maskawa ・４元模型ではCPは破れない ・未知の粒子の存在 ・６元模型は可能性の一つとして指摘

  10. 1974 discovery of J/ψ • 1975discovery of τ • 1975Pakvasa, Sugawara • 1976Ellis, Gaillard, Nanopoulos • 1977 dicovery of Υ • 1979CP in B-meson system B-Factory

  11. Conclusion CP violation will continue to be challenging both experimentally and theoretically

  12. Dyon Charged particle dual N=2 supersymmetric gauge theory Electric Dipole Moment (edm) andq-term P, T edm Kugo, Tokunaga, M.K.
