The 2015 Nobel Prize for Physics has been awarded to two teams that pioneered the discovery that neutrinos switch between different flavours.
TAKAAKI KAJITA and ARTHUR MCDONALD were named at a news conference in Stockholm, Sweden.The Secretary General of the Royal Swedish Academy of Sciences, GORAN HANSSON, said this year’s prize is about changes of identity among some of the most abundant inhabitants of the Universe.
The winners are reputed for leading two teams which made key observations of the particles inside big underground instruments in Japan and Canada.
The BBC reports that neutrinos are ubiquitous subatomic particles with almost no mass and which rarely interact with anything else, making them very difficult to study.
