Nobel Prize for Physics goes to Takaaki Kajita and Arthur B McDonald, for neutrino work that helped understand ‘nature’s most elusive particles’
Neutrinos are very common fundamental particles in the universe — but we still don’t know all that much about them

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
Your support makes all the difference.Two physicists have won the Nobel Prize for Physics for their work to discover that neutrinos have a mass — one of the few things that we know about the elusive particles.
Japanese Takaaki Kajita and Canadian Arthur B. McDonald were given the award today “for the discovery of neutrino oscillations, which shows that neutrinos have mass”.
The award was given to the scientists “for their key contributions to the experiments which demonstrated that neutrinos change identities”, the committee said. “This metamorphosis requires 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.”
Scientists know very little about neutrinos and the fact that they hardly ever interact makes them very difficult to study. For half a century scientists thought that they had no mass — but the discovery at the turn of the millennium that they actually have mass led to the work that was recognised by 2015’s prize.
