| Outline of Final Research Achievements |
A gauge boson with mass of order MeV has been suggested by recent cosmic neutrino flux observation and nucleus decay experiments. Such a light gauge boson should be a new particle since no candidates exist in the standard model particle physics.
In this project, we studied possibilities on detecting such a light gauge boson at collider experiments and direct dark matter searches. We proposed an appropriate processes at expeiments to search the gauge boson, and showed parameter regions which can be examined at the experiments. These results enables us to search the light gauge boson by analyzing expeimental data provided by future expements.
