Timeline

Yoshio Koide (小出 義夫) is a Japanese theoretical physicist working in particle physics.

Koide is known for his eponymous Koide formula, which some physicists think has great importance but which other physicists contend is merely a numerical coincidence.

1967

Koide earned in 1967 a B.Sc.

with major in physics and in 1967 a M.Sc.

in Theoretical Elementary Particle Physics from Kanazawa University.

1970

In 1970, he received his Doctor of Science degree from Hiroshima University with a thesis “On the Two-Body Bound State Problem of Dirac Particles”.

1972

After working as a postdoc in the physics department of Hiroshima University and then a postdoc in the applied mathematics department of Osaka University, he became, from 1972 to 1973, a Lecturer in the School of Science and Engineering, Kinki University, Osaka.

1973

Koide was Assistant Professor (1973-1977) then Associate Professor (1977-1987) of General Education, Shizuoka Women's University, Shizuoka.

1982

He published the famous Koide formula in 1982 with a different presentation in 1983.

Originally, Koide's proposed charged lepton mass formula was based on a composite model of quarks and leptons.

1986

In 1986 he was a visiting professor at the University of Maryland and in 2002 a visiting researcher at CERN.

1987

From April 1987 to March 2007 he was a Professor of Physics at University of Shizuoka, Shizuoka and then retired as professor emeritus.

1990

In a 1990 paper, from the standpoint that the charged leptons are elementary, by introducing a scalar boson with (octet + singlet) of a family symmetry U(3), Koide re-derived the charged lepton mass formula from minimizing conditions for the scalar potential.

2007

Koide was from April 2007 to March 2009, a guest professor at Research Institute for Higher Education and Practice, Osaka University, then from April 2009 to March 2011 a guest professor and from April 2011 a guest researcher at Osaka University, and from April 2010 a professor, Department of Maskawa Institute, Kyoto Sangyo University, Kyoto.

In the composite model of mesons, Koide's thesis demonstrated that a mass m of a composite particle which consists of the rest masses m_1,m_2 cannot be lighter than except for the case m_1 = m_2 when JP is not = 0-.

This offered a severe problem for the quark model.

(Koide’s work was done before the establishment of QCD.)

Katuya and Koide predicted that lifetimes of D± and D0 should be considerably different from what was at that time the conventional anticipation tau(D±)= tau(D0).

Their prediction of these lifetimes was the first in the world prior to the experimental observation.

2009

In 2009, he related the neutrino mixing matrix to the up-quark mass matrix.

Koide and Hiroyuki Nishiura have published articles on a quark and lepton mass matrix model and a neutrino mass matrix model.
