Descrizione
The T2K (Tokai-to-Kamioka) experiment is a long-baseline oscillation experiment situated in Japan. A high intensity muon neutrino beam is sent from the JPARC proton accelerator complex in Tokai to the SuperKamiokande detector, 295 Km away. The primary goals of T2K are precise measurements of the electron neutrino appearance and muon neutrino disappearance parameters.
The T2K collaboration has recently firmly established, the observation of the appearance of electron neutrinos from muon neutrino beam with a significance of 7.3 sigma.
Furthermore T2K has become the world leading experiment concerning the measurement of the mixing angle theta_23 and set the first limit at 90% CL on the still unknown parameter delta_CP.
To further enhance its physics potential, T2K has also started in 2014 to collect data in antineutrino mode and the first results are being presented at winter conferences.
In this seminar I will review the neutrino oscillations phenomenon before focusing on the T2K experiment and its recent results. To give a complete overview of the complexity of the experiment I will also review the complementary measurements needed to achieve the oscillation measurements.
