The JENNIFER2 project aims to produce synergy and knowledge sharing among experimental particle physics groups searching for signal of new physics in neutrino and flavour physics, exploiting the discovery potentialities of experimental facilities located in Japan.
The Standard Model of elementary particles has been very successful in explaining a wide variety of existing experimental data. However, in spite of its tremendous success, the SM does not answer several fundamental questions, which require to be investigated with various complementary approaches, using different “messenger” particles. The flavour sector of quarks and leptons is a privileged field to look for the presence of new physics effects, by profiting from a closer collaboration among different experimental communities. Moreover, neutrino physics requires the use of very large volume detectors, which can both be used for accelerator produced neutrinos and for cosmic one, creating another stimulating synergy.
JENNIFER2 project aims to investigate such fascinating scenarios, both by an aggressive program of data mining at Belle II and T2K and by developing innovative particle detectors to meet even more challenging performance requirements for present and future experiments. The knowledge exchange among the Belle II, T2K and HyperK scientific communities, started by the JENNIFER project, already produced some new ideas towards more performant detectors and techniques. JENNIFER2 will allow to realize part of them, via the upgrade of T2K experiment with a new near detector, and to continue developing many other techniques in a very synergic way. Photon detection plays a special role in all experimental applications and JENNIFER2 will provide an invaluable space to coordinate and contaminate few challenging developments in this field, while techniques related to computing, data acquisition, statistical methods and theory-experiment interface will be for the first time jointly addressed by the collider and neutrino communities.
