The T2K experiment is originally designed to look for neutrino oscillations, by sending neutrino beams over 295 km. However, the experiment itself can measure and test a variety of physics. I am interested in to study both neutrino interaction physics and new physics search, including dark photon, Lorentz violation, light WIMP, etc, using existing T2K near detectors.
Neutrino interaction physics is an important subject to study, especially after the discovery of the importance of multi-nucleon correlations in this field. The axial current structure measured by neutrinos are often inaccessible by electron scattering experiments (which mainly sensitive to vector current part), and any data taken by neutrino beam is valuable to understand the axial structure of nuclear targets. On top of that, neutrino interaction is one of the most important systematics for current and future neutrino oscillation experiments, including T2K, NOvA, DUNE, Hyper-Kamiokande, and PINGU. Therefore, understanding of this is also an important task for oscillation experiments.
A rich structure of T2K near detector system can be also used to study new physics. I am especially interested in to understand so-called "short baseline anomalies", reported from LSND, MiniBooNE, etc. These experiments observed unknown excesses of electron neutrino oscillation candidate events. There are several new physics models for these, and some of them can be tested at T2K near detector system.
