Neutrino Research at Super-Kamiokande

the University of Hawaii Connection


University of Hawaii members of the Super-Kamiokande Collaboration are three professors from the Department of Physics and Astronomy at UH Manoa and two graduate students, Atsuko Kibayashi and Dean Takemori.

Prior to coming to Hawaii in 1980, John G. Learned was one of the original seven people who formed the IMB experiment. He has been one of the leaders in the Super-Kamiokande Collaboration in the drive to understand the data and the implications of oscillations and helped write the presently discussed paper. He can be reached at 808 956-2964, jgl@uhheph.phys.hawaii.edu, or via www.phys.hawaii.edu/~jgl

Shigenobu Matsuno has long been involved with the IMB project and was resident physicist in Cleveland for two years. He is leader of one of the Super-Kamiokande analysis groups. He can be reached at 808 956-2966 or shige@uhheph.phys.hawaii.edu

Victor J. Stenger has been working on neutrino physics for many years. He has carried out neutrino flux calculations. He can be reached at 808 956-2942 or vjs@uhheph.phys.hawaii.edu.

All three faculty members were involved in the DUMAND Project, an attempt to conduct neutrino astronomy under the ocean near Hawai. That project is now being carried on in the Mediterranean. Over the years the IMB, DUMAND and Super-Kamiokande projects have produced 14 PhDs from the University of Hawaii and brought about $8 million in research funds to the University.

UH team members were the leaders in the IMB experiment in finding the neutrino burst from Supernova 1987A (23 February 1987), termed by many the major high energy physics observation of the decade. This burst of neutrinos coming from the collapse of a star in the nearby small galaxy called the Large Magellanic Clouds and located 150,000 light years away produced the first direct evidence that massive stars actually do end their lives in gravitational collapse to a neutron star, with the emission of a staggering pulse of neutrinos. More than 150 publications used these observations to extract many new facts about neutrinos previously untested in the laboratory.

The Hawaii group has been involved in the Super-Kamiokande experiment since the U.S. IMB group merged with Super-Kamiokande in 1994. The merger was initiated by UH Manoa graduate Steven T. Dye, then a researcher at Boston University and now associate dean at Hawaii Pacific University.

December 1997 UH Manoa graduate John Flanagan, now working at the KEK laboratory in Japan, wrote the first dissertation on Super-Kamiokande, using the contained neutrino interaction data discussed in the attached Q&A for neutrino oscillations analysis. Another former UH Manoa graduate student, Robert Svoboda, now a professor at Louisiana State University, is a Super-Kamiokande analysis group leader.
The project has produced more than good physics--both Flanagan and Svoboda met their wives in the Super-Kamiokande Project and were married in Hawaii last Fall.

The UH elementary particle theory group has also been actively engaged in studying neutrino phenomenology, particularly as it relates to Super-Kamiokande. Professor Sandip Pakvasa is one of the world's experts on neutrino phenomena and neutrino oscillations in particular. Professor Xerxes Tata and Adjunct Professor Walter Simmons also have participated in various neutrino phenomena calculations relating to the Super-Kamiokande Project.

There is a long standing and active interest in the study of neutrinos in the UHM Department of Physics and Astronomy, which makes it an exciting and stimulating place to work for those thrilled by neutrinos and a great place to learn for those seeking the most up-to-date study in high energy physics.
