Nobel Prize winner to explain Universe's most elusive particles at public talk in Sheffield


The winner of the 2015 Nobel Prize in Physics will be presenting a public lecture at the University of Sheffield on Thursday, 1st June 2017.

Professor Takaaki Kajita, the Director of the Institute for Cosmic Ray Research (ICRR), University of Tokyo, will be talking about the research that led to his discovery of atmospheric neutrino oscillations for which he and Arthur B. McDonald were awarded the Nobel Prize.

Dr Matthew Malek from the Department of Physics and Astronomy at the University of Sheffield is hosting Professor Kajita during his visit to Sheffield and said, “It is a complete honour to host Professor Kajita and to have him talk at the University. Kajita

“Professor Kajita is one of the world’s greatest physics minds and his talk will be an amazing opportunity for everyone who has an interest in physics, the big bang and the Universe, from school children to senior academics, to hear him speak and talk to him about this fascinating subject.”

Neutrinos are nature's ghosts and are among the lightest subatomic particles. There are more of these elusive particles in the universe than any other known type of matter, yet they will almost never interact. As you read this, over one trillion neutrinos per second will pass through your body, yet none will ever hit you.

Proving the existence of neutrinos was a massive challenge for physicists due to their having almost no mass and no charge. However, Professor Kajita’s research eventually led to confirmation of their existence and we now have the chance to unlock one of the major unsolved mysteries of physics: Why is there any matter in the Universe today?

Professor Kajita’s talk will take place at The Diamond, University of Sheffield on Thursday 1st June at 11:00. Tickets are free, but if you would like to attend, please register via the event website.
