Our group is strongly implied in the T2K collaboration, which researches the electronic neutrinos appearance from a muon neutrinos beam.

 

JPARC is the new particle accelerator which Japan has provided. It will project in a few months a beam of neutrinos with an intensity unseen before to the SuperKamiokande detector 295km away. A near detector is also installed at 280m.

 

Our group develops in particular the TPC Micromega which enables this near detector to measure the ratio of charged particles on neutral particles.

 

We are participating also to the development of reconstruction tools for the far detector SuperKamiokande. This water Cerenkov detector uses light rings generated by relativistic charged particles, especially electrons and muons resulting from quasi-elastic interactions of the respective neutrinos. The study of those rings enables us to identify the particle type, and thus to select the signal (electron neutrinos from oscillation) and reject the background (pions and muons created by muon neutrinos interactions and electron neutrinos intrinsic to the neutrinos beam).
