Question: Arthur B. McDonald shared the Nobel Prize in Physics for 2015 with the Japanese physicist known for what type of work?

full_context: Document 1: List of Japanese Nobel laureates: Since 1949, there have been twenty-five Japanese winners of the Nobel Prize (Swedish: "Nobelpriset" ). The Nobel Prize is a Sweden-based international monetary prize. The award was established by the 1895 will and estate of Swedish chemist and inventor Alfred Nobel. It was first awarded in Physics, Chemistry, Physiology or Medicine, Literature, and Peace in 1901. An associated prize, The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, was instituted by Sweden's central bank in 1968 and first awarded in 1969.
Document 2: Nobel Prize in Physics: The Nobel Prize in Physics (Swedish: "Nobelpriset i fysik" ) is a yearly award given by the Royal Swedish Academy of Sciences for those who conferred the most outstanding contributions for mankind in the field of physics. It is one of the five Nobel Prizes established by the will of Alfred Nobel in 1895 and awarded since 1901; the others being the Nobel Prize in Chemistry, Nobel Prize in Literature, Nobel Peace Prize, and Nobel Prize in Physiology or Medicine.
Document 3: Leo Esaki: Reona Esaki (江崎 玲於奈 "Esaki Reona", born March 12, 1925), also known as Leo Esaki, is a Japanese physicist who shared the Nobel Prize in Physics in 1973 with Ivar Giaever and Brian David Josephson for his discovery of the phenomenon of electron tunneling. He is known for his invention of the Esaki diode, which exploited that phenomenon. This research was done when he was with Tokyo Tsushin Kogyo (now known as Sony). He has also contributed in being a pioneer of the semiconductor superlattices.
Document 4: Massless particle: In particle physics, a massless particle is an elementary particle whose invariant mass is zero. The two known massless particles are both gauge bosons: the photon (carrier of electromagnetism) and the gluon (carrier of the strong force). However, gluons are never observed as free particles, since they are confined within hadrons. Neutrinos were originally thought to be massless. However, because neutrinos change flavor as they travel, at least two of the types of neutrinos must have mass. The discovery of this phenomenon, known as neutrino oscillation, led to Canadian scientist Arthur B. McDonald and Japanese scientist Takaaki Kajita sharing the 2015 Nobel prize in physics.
Document 5: Susumu Tonegawa: Susumu Tonegawa (利根川 進 "Tonegawa Susumu", born September 6, 1939) is a Japanese scientist who was the sole recipient of the Nobel Prize for Physiology or Medicine in 1987, for his discovery of the genetic mechanism that produces antibody diversity. Although he won the Nobel Prize for his work in immunology, Tonegawa is a molecular biologist by training and he again changed fields following his Nobel Prize win; he now studies neuroscience, examining the molecular, cellular and neuronal basis of memory formation and retrieval.
Document 6: Arthur B. McDonald: Arthur Bruce McDonald, {'1': ", '2': ", '3': ", '4': "} (born August 29, 1943) is a Canadian astrophysicist. McDonald is the director of the Sudbury Neutrino Observatory Institute and holds the Gordon and Patricia Gray Chair in Particle Astrophysics at Queen's University in Kingston, Ontario. He was awarded the 2015 Nobel Prize in Physics jointly with Japanese physicist Takaaki Kajita.
Document 7: Davis Earle: Dr. Eric 'Davis' Earle (died 24 December 2016) was a Canadian nuclear physicist. A Rhodes Scholar, he worked at Chalk River and helped organize Sudbury Neutrino Observatory as part of the project team whose director, Arthur B. McDonald, won the 2015 Nobel Prize in Physics.
Document 8: J. Michael Kosterlitz: John Michael Kosterlitz (born June 22, 1943) is a British born Anglo-American physicist. He is a professor of physics at Brown University and the son of biochemist Hans Kosterlitz. He was awarded the 2016 Nobel Prize in physics along with David Thouless and Duncan Haldane for work on condensed matter physics.
Document 9: Adam Riess: Adam Guy Riess (born December 16, 1969) is a U.S. astrophysicist and Bloomberg Distinguished Professor at Johns Hopkins University and the Space Telescope Science Institute and is known for his research in using supernovae as cosmological probes. Riess shared both the 2006 Shaw Prize in Astronomy and the 2011 Nobel Prize in Physics with Saul Perlmutter and Brian P. Schmidt for providing evidence that the expansion of the universe is accelerating.
Document 10: Nicholas B. Suntzeff: Nicholas B. Suntzeff (born November 22, 1952, San Francisco) is an American University Distinguished Professor and holds the Mitchell/Heep/Munnerlyn Chair of Observational Astronomy in the Department of Physics & Astronomy at Texas A&M University where he is Director of the Astronomy Program. He is an observational astronomer specializing in cosmology, supernovae, stellar populations, and astronomical instrumentation. With Brian Schmidt he founded the High-z Supernova Search Team, which was honored with the Nobel Prize in Physics in 2011 to Schmidt and Adam Riess.
Document 11: Reiner Kruecken: Reiner Kruecken is Deputy Director at TRIUMF, Canada’s National Laboratory for Particle and Nuclear Physics. He joined TRIUMF in February 2011 after 8 1/2 years at the Technical University Munich, Germany, where he held the chair (C4) for Experimental Physics of Hadrons and Nuclei. From 2011 to 2015 Kruecken was the Head of the Science Division at TRIUMF. Kruecken received his Ph.D. in nuclear physics from the University of Cologne in 1995. After a postdoctoral fellowship at Lawrence Berkeley National Laboratory he moved to Yale University in 1997 where he was an Assistant Professor at the Physics Department and the A.W. Wright Nuclear Structure Laboratory until he moved to Munich in 2002. His current research interests are in the area of the structure of exotic nuclei, nuclear astrophysics, as well as applications of nuclear physics methods to radiation biology and medicine.
Document 12: Donald B. Campbell: Donald B. Campbell is an Australian-born astronomer and Professor of Astronomy at Cornell University. Prior to joining the Cornell faculty he was Director of the Arecibo Observatory in Puerto Rico for seven years. Campbell's research work is in the general area of planetary studies with a concentration on the radio-wavelength-scattering properties of planets, planetary satellites, and small bodies. His work includes studies of Venus, the Moon, the Galilean satellites of Jupiter, Titan, as well as comets and asteroids. Campbell observed near-Earth asteroid 433 Eros, which was the first asteroid detected by the Arecibo Observatory radar system.
