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, but it does not answer several fundamental questions, such as the origin of the dark matter (which we know from the Cosmological Model it is responsible for 90% of the universe mass), the mater-antimatter asymmetry (which can be explained only with a sizeable violation of the so called CP symmetry) and the observed pattern of fermions mass spectrum.
For all these reasons physicists are looking for the signals of new particles and interactions which can either be directly produced at the energy frontier of the available particle acceleration technology, either appear as tiny deviations from SM expectations in rare processes at lower energy. JENNIFER2 project is dedicated to this second approach, with two different techniques: the so called “intensity frontier”, where very intense particle accelerators produce an enormous number of events which are recorded and analysed with precision detectors, and the neutrino physics, where large volume underground detectors reconstruct the rare interactions of neutrinos with matter, both accelerator produced and cosmic ones. The first technique is represented by the Belle II experiment working at the SuperKEKB accelerator, while the second one is the T2K experiment and its future development in the HyperK project.
JENNIFER2 includes both detector and technology developments for the upgrade and improvement of the experiments in the above stated fields, both the challenging data analyses that will produce stringent limits on new phenomena or evidences for them. Moreover JENNIFER2 puts together the scientist communities working at the intensity frontier and at the neutrino underground experiments, and aims to produce important synergies in several technologic issues.
Finally, JENNIFER2 includes a number of outreach activities towards different societal targets, to promote both the general knowledge of the fundamental physics and its implications, and the promotion of the scientific collaboration between Europe and Japan.
