| Outline of Final Research Achievements |
We have systematically explored methods to probe whether the unified theory called string theory is the ultimate theory of Nature in terms of observations of phenomena caused by fields and particle in the hidden sector specific to superstring theory. As a result, we have proposed lots of new methods such as the observation of gravitational waves produced by the interaction between black holes and a scalar field called axion, observations of gamma rays from high-energy astrophysical objects and cosmic infrared background radiations, observations of electromagnetic and gravitational waves passing through axion dark matter, new particle searches by accelerator experiments, CMB observations of inflation in the early universe. Further, we have constructed some concrete examples of superstring compactifications that are consistent with both the standard model of elementary particles and cosmology.
