T2K finds possible CP violation in neutrinos

Kendall MahnThe T2K experiment, in which our Professor Kendall Mahn is an analysis co-coordinator, published a paper in Nature with the possible discovery of CP violation in neutrinos. Specifically, the experiment analyzed almost a decade's worth of data from the Super Kamiokande neutrino detector in Japan and found evidence for a difference between the way neutrinos and antineutrinos oscillate by comparing the number of each that reached Super Kamiokande with a flavor different from the one they had been created with. If confirmed by future studies, this would represent a groundbreaking advance towards understanding the fundamental reason for the predominance of matter over antimatter in our universe. On a more local level, it is exciting, fundamental discoveries like these that make the long flights to Japan worth it for Professor Mahn and her team at MSU.
