| Outline of Final Research Achievements |
The research field of gravitational waves has attracted a broad public interest as shown by the Nobel prize of physics in 2017. The observational results have been so far consistent with the prediction of Einstein's theory of general relativity within the observational accuracy. On the other hand, recent researches on fundamental physics suggest a possibility that there may exist extra polarizations of gravitational waves which do not live in the theory of general relativity. Our research shows that such extra polarizations can be tested even by the current four detectors. Furthermore, we present a specific condition for enabling the new test.
