2005 J. J. Sakurai  Prize in Theoretical 
Particle Physics to Susumu Okubo Professor of
Physics University of Rochester (and UR PhD
58) "For  ground breaking investigations into
the pattern of hadronic masses and decay rates,
which provided essential clues into the
development of the quark model, and for
demonstrating that CP Violations permits partial
decay rate asymmetries"
Prof. Okubo received his B.S. in Physics (1952)
from the University of Tokyo, Japan and his Ph.D.
in Physics (1958) from the University of
Rochester. After one year of postdoctoral
research at Rochester he went to the University
of Napoli, Italy (1959-60) and CERN, Switzerland
(1960-61). He returned to the University of
Rochester in 1962 as a Senior Research Associate
in the Department of Physics and was promoted to
full Professor in 1964. He is the author of the
book, Introduction to Octonian and Other
Non-associative Algebras in Physics (Cambridge
Univ. Press, 1995). He was awarded a Nishina
Prize in 1976 from the Nishina Foundation in
Japan for his contributions to particle physics.
He was a recipient of Guggenheim (1966) and Ford
Foundation (1969) Fellowships. He is a Fellow of
the American Physical Society. Prof. Okubo's
primary research interest is in the area of
Theoretical High Energy Physics and mathematical
physics. In particular, his recent works have
focused on applications of Lie algebras and other
non-associative algebras in both physics and
mathematics.

Particle Physics ( since it was established in

insightful contributions to elucidating the
structure of the nucleon, using a wide variety of
probes, tools and methods at many laboratories."

decisive in all aspects of the experiment." 2000

study of the b quark with the CLEO
collaboration particularly the discovery and
measurement of b semileptonic decay, the b to s
Penguin decay process, and the b to u weak
transition. In addition, his contributions led to
substantial improvements in understanding the
flavor sector of the Standard Model and the
Cabibbo-Kobayashi-Maskawa matrix of weak quark
couplings." 1998 David Robert Nygren (Lawrence
Berkeley National Laboratory) "For the concept,
development, and application of the time
projection chamber (TPC), enabling unprecedented
studies of complex topologies of charged
particles produced in high energy collisions of
interest to both high energy and nuclear
physics." 1997 Henning Schröder (DESY) and Yuri
Zaitsev (Moscow Physical Technical Institute)
"For their leading role in the first
demonstration of mixing in the BO - B-O system.
The unexpectedly large value of the mixing
parameter provided indirect evidence for a large
top quark mass and has greatly enhanced the
possibility for studying CP violation in B meson
decays. This capability has encouraged a
worldwide effort to determine whether the small
CP violation in K decay is a reflection of a
fundamental parameter characterizing transitions
of quarks among the three generations." 1996
Gail G. Hanson (Indiana University) and Roy F.
Schwitters (University of Texas - Austin ) "Gail
Hanson and Roy Schwitters are honored for their
separate contributions which together provided
the first clear evidence that hadronic final
states in ee? annihilation, which are largely
composed of spin 0 and spin 1 particles,
originate from the fragmentation of spin 1/2
quarks. Gail Hanson observed hadron jets and
determined the jet axis by developing and
applying the spheric-ity analysis to the hadrons
in e e? events. She showed that events become
more jet?like with increasing energy, contrary to
what one expects from a simple phase space
production mechanism. Using the beam
polarization, she showed that the observed
azimuthal distribution of the jet axis was that
expected from the production of spin 1/2 quarks
that fragment into hadrons." 1995 Frank J.
Sciulli (Columbia University) "For his
contribution to a seminal set of high energy
neutrino experiments at Fermilab. These
experiments played an important role in
establishing the existence of weak neutral
currents they established accurate
neutrino-nucleon cross sections and accurate
values of basic electroweak parameters they set
important limits on neutrino oscillations and
they fit sum rules that helped establish the
physical reality of quarks." 1994 Thomas J.
