Memories of Jiro at Kyoto, SLAC and Hiroshima Ken Sasaki Yokohama National University Towards precision QCD physics dedicated to the memory of Jiro Kodaira

Jiro at Kyoto Graduated from Kyoto Univ. in 1974 Finished Ph.D in RA at YITP, Kyoto Univ. We were young, anticipating bright future and happy ◆ Particle physics group at Kyoto Univ. at that time Students were admitted into faculties ’ offices ◆ Jiro was at Matsuda ’ office for years.

At Mt. Atago At home of M. Kobayashi (1976) (1977 ?)

I shared office with Jiro for six months in His desk was always tidy and cleaned up His notebooks Jiro ’ note Tsuneo ’ s note My note

He loved coffee He loved sake He loved to play GO He fell in love with Mieko Analysis of hadronic decays of Ψ/J particles in generalized Veneziano models, J. Kodaira and K. S. ; Phys. Rev. D17, (1978) Analysis of hadronic decays of Ψ/J particles in generalized Veneziano models.II. The Ψ -> 3πdecay, J. Kodaira and K. S. ; Phys. Rev. D18, (1978) Analysis of hadronic decays of Ψ/J particles in generalized Veneziano models III. The Ψ -> KKπdecay, J. Kodaira and K. S. ; Phys. Rev. D18, (1978) QCD effects in polarized electroproduction, J. Kodaira, S. Matsuda, T. Muta, T. Uematsu and K. S. ; Phys. Rev. D20, (1979) QCD higher order effects in spin-dependent deep inelastic electroproduction, J. Kodaira, S. Matsuda, T. Uematsu and K. S. ; Nucl. Phys. B159, (1979) Study of the reaction pp -> Ψn in generalized Veneziano models, J. Kodaira and K. S. ; Lett. Nuovo Cim. 26, (1979)

I visited his parents’ home at Suwa in 1979 Jiro grew up at Suwa Suwa Taisha Lake Suwa

We were treated to regional specialites Horse meat Locusts Bee embryos “ Catch of the day” from Lake Suwa

Jiro at SLAC JSPS Fellow at SLAC (Postdocs: J. Kodaira, L. Trentadue, S. Parke, J. Polchinski, G. Bodwin, E. Kovac, C. Peterson, S. Gupta, …. …, K. S. He loved cars (He drove a big red Cadillac) Picnic at SLAC (1980)

He loved wine Wine tasting at Napa Valley (1980)

Jiro at Hiroshima at Hiroshima Univ. He was an excellent teacher and mentor. He supervised many students for their Ph.D theses Mt. Aso in Kyushu (1996)

He loved cars (He drove a BMW) He was a gourmet Lobster One of his favorite places Sole

He organized International Symposium on “QCD Corrections and New Physcs” at Hiroshima in 1997 The mass of the lightest supersymmetric Higgs boson beyond the leading logarithm approximation, J. Kodaira, Y. Yasui and K. S.; Phys. Rev. D50, (1994) The background field method: Alternative way of deriving the pinch technique's results, S. Hashimoto, J. Kodaira, Y. Yasui and K. S.; Phys. Rev. D50, (1994) More on the Burkhardt-Cottingham sum rule in QCD, J. Kodaira, S. Matsuda, T. Uematsu and K. S.; Phys. Lett. B345, (1995)

It is very sad to admit that Jiro is no longer with us but I WILL never forget his contributions to particle physics and also our friendship for more than 30 years.
