• Resumen

  • Neutrinos and their antimatter counterparts each come in three flavors: electron, muon and tau, which they can switch, or oscillate, between. The T2K experiment in Japan watches for these oscillations as neutrinos travel 295 km between the J-PARC accelerator in Tokai and the Super-Kamiokande detector in Kamioka. The idea is that physics should remain basically unchanged if one replaces all particles with their respective antiparticles. It appears to hold true for nearly all particle interactions, and implies that the universe should have produced the same amount of matter and antimatter in the big bang.
