Expert on T2K experiment

A breakthrough for the Japan-based T2K experiment involves a “ghostly” particle—the neutrino, which has the ability to pass through walls (or even the entire earth) without difficulty—whose spontaneous “flip-flopping” from one type into another brings us one step closer to understanding why matter and antimatter created at the Big Bang did not simply annihilate each other. The University of Victoria is playing a key role in the T2K collaboration, with the following expert available to comment on this scientific milestone:

Dean Karlen (R. M. Pearce Professor of Physics, UVic’s Department of Physics and Astronomy; TRIUMF) is director of UVic’s Victoria Subatomic Particle and Accelerator Research Centre and one of the lead investigators in the T2K project. “We saw the first hints of this ‘flip-flopping’ in 2011,” he says, “but when we’re dealing with science at the edge, there are uncontrolled random factors and therefore there are standards about how certain we need to be before announcing a discovery. T2K has reached that threshold.” More on T2K UVic and neutrinos (Office: 250-721-6585 or email: karlen@uvic.ca)

The international Tokai to Kamioka (T2K) collaboration made the announcement July 19, including a news release (triumf.ca/t2k) from TRIUMF, Canada’s national laboratory for particle and nuclear physics.

TRIUMF is owned and operated as a joint venture by a consortium of Canadian universities including UVic. It attracts top physicists from around the world who collaborate on research related to particle and nuclear physics, molecular and materials science, and nuclear medicine. TRIUMF was co-founded by UVic, UBC and SFU in the 1960s.
