AbstractTwo polarizations of the gravitational waves, the plus and cross modes, are derived from general relativity. However, alternative theories of gravity can yield the gravitational waves with up to six polarizations. Searching for the polarizations beyond plus and cross is an important test of general relativity. In principle, one spaceborne detector, like LISA, could measure the gravitational wave polarizations from a long time observation with its orbital motion. With comparable sensitivities, the joint LISA and TAIJI missions will improve the observations on the polarization predictions of theories beyond general relativity. In this work, a class of parametrized post-Einsteinian waveforms is employed to describe the alternative polarizations, and six parametrized post-Einsteinian parameters quantifying the deviation from the general relativity waveforms are examined by using the LISA-TAIJI network. Our results show that the measurements on amplitudes of alternative polarizations from joint LISA-TAIJI observation could be improved by more than 10 times compared to LISA single mission in an optimal scenario.
