Memories of Jiro at Kyoto, SLAC and Hiroshima

Ken Sasaki Yokohama National University

Towards precision QCD physics 　　　　　　　　 dedicated to the memory of Jiro Kodaira 07.3.10

Jiro at Kyoto Graduated from Kyoto Univ. in 1974 Finished Ph.D in 1979 1979-1980 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 1976-77

His desk was always tidy and cleaned up His notebooks

He loved coffee He loved sake He loved to play GO He fell in love with Mieko

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 1980-1982 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 1983-2005 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, 7035-7041 (1994) The background field method: Alternative way of deriving the pinch technique's results ,

J. Kodaira, S. Matsuda, T. Uematsu and K. S.; Phys. Lett. B345, 527-531 (1995)

It is very sad to admit that Jiro is no longer with us

but I WILL never forget his contributions to particle physicsand also our friendship for more than 30 years.
