Abstract: In general relativity, a gravitational wave (GW) has two polarization modes, while in modified gravity, the GW is allowed to have additional polarizations. Thus, the observation of the GW polarizations can be utilized for the test of gravity theories. In this letter, we focus on a stochastic GW background (GWB) and classify the polarization modes into tensor, vector, and scalar modes, and then show that the future space-based detectors such as BBO and DECIGO can successfully separate and probe the GWB with the non-Einsteinian polarization modes.
