Makoto Kobayashi
The 2008 physics Nobel laureates Yoichiro Nambu, Toshihide Maskawa and Makoto Kobayashi, who received their awards for work on symmetry breaking, all came under his tutelage and influence. The baryonic mixing in the weak current in the Nagoya Model was the inspiration for the later Cabibbo–Kobayashi–Maskawa matrix of 1973, which specifies the mismatch of quantum states of quarks, when they propagate freely and when they take part in weak interactions. Physicists however, generally attribute the introduction of a third generation of quarks (the "top" and "bottom" quarks) into the Standard Model of the elementary particles to that 1973 paper by Kobayashi and Maskawa.
