What is the T2K Experiment?

The T2K (Tokai to Kamioka) experiment is a neutrino oscillation experiment in Japan designed to study how neutrinos change their "flavor" (type) as they travel over a long distance.

What is the main objective of the T2K Experiment?

T2K's primary goal is to precisely measure neutrino oscillation parameters, particularly the mixing angle θ₁₃, and to search for CP violation in the lepton sector, which could help explain the universe's matter-antimatter asymmetry.

Where are the main components of the T2K Experiment located?

The experiment uses a neutrino beam generated at the J-PARC facility in Tokai, Ibaraki, and detects it 295 km away at the Super-Kamiokande detector in Kamioka, Gifu, Japan.

What are neutrino oscillations?

Neutrino oscillations are a quantum mechanical phenomenon where a neutrino created with a specific lepton flavor (electron, muon, or tau) can later be measured to have a different flavor. This implies neutrinos have mass.
