Berkeley Lab physicists and engineers are among the leaders of the
unique Daya Bay Reactor Neutrino Experiment, where Chinese and American
scientists, with colleagues from Russia, Taiwan, and the Czech Republic,
have come together to investigate a peculiar phenomenon related to
so-called neutrino mixing. Kam-Biu Luk of Berkeley Lab’s Physics
Division, a professor of physics at the University of California at
Berkeley, is Daya Bay’s scientific co-spokesperson with Yifang Wang of
Beijing’s Institute of High Energy Physics. Bill Edwards of the Lab’s
Physics Division is the U.S. Project and Operations Manager.
What the researchers find at Daya Bay will bear on some of the most
intriguing questions in basic physics: how much do different kinds of
neutrinos weigh? And which kind is the heaviest? By weighing neutrinos
scientists hope to learn how electrons and their cousins, muons and tau
particles, came into existence in the moments after the big bang. The
answers could explain why there is more matter than antimatter in the
universe – and indeed why there is any matter at all.
