Nobel Laureates Takaaki Kajita & Arthur B. McDonald
2015 Nobel Prize in Physics
Takaaki Kajita and Arthur B. McDonald were awarded this year’s Nobel Prize in Physics for the discovery of neutrino oscillations, which shows that neutrinos have mass
October 08, 2015
This year’s Nobel Prize in Physics laureates Takaaki Kajita (Japan) and Arthur B. McDonald (Canada) have been rewarded for their key contributions to the experiments which demonstrated that neutrinos change identities, determining that neutrinos have mass. The discovery has changed our understanding of the innermost workings of matter and can prove crucial to our view of the universe.
Around the turn of the millennium, Takaaki Kajita presented the discovery that neutrinos from the atmosphere switch between two identities on their way to the Super-Kamiokande detector in Japan.
Meanwhile, the research group in Canada led by Arthur B. McDonald could demonstrate that the neutrinos from the Sun were not disappearing on their way to Earth. Instead they were captured with a different identity when arriving to the Sudbury Neutrino Observatory.
The discovery rewarded with this year’s Nobel Prize in Physics have yielded crucial insights into the all but hidden world of neutrinos. After photons, the particles of light, neutrinos are the most numerous in the entire cosmos. The Earth is constantly bombarded by them.
Many neutrinos are created in reactions between cosmic radiation and the Earth’s atmosphere. Others are produced in nuclear reactions inside the Sun. Thousands of billions of neutrinos are streaming through our bodies each second. Hardly anything can stop them passing; neutrinos are nature’s most elusive elementary particles.
Now the experiments continue and intense activity is underway worldwide in order to capture neutrinos and examine their properties. New discoveries about their deepest secrets are expected to change our current understanding of the history, structure and future fate of the universe.
ICFO congratulates these new laureates and celebrates their important accomplishments.
