Testing massive-field modifications of gravity via gravitational waves.

The direct detection of gravitational waves now provides a new channel for testing gravity theories. Despite that the parametrized post-Einsteinian framework is a powerful tool to quantitatively investigate the effects of modifications to gravity theory, the gravitational waveform in this framework is still extendable. One such extension is to take into account the gradual activation of dipole radiation due to massive fields, which are still only very weakly constrained if their massmis greater than 10(-16) eV from pulsar observations. Ground-based gravitational-wave detectors (LIGO, Virgo, and KAGRA) are sensitive to this activation in the mass range 10(-14) eV less than or similar to m less than or similar to 10(-13) eV. Hence, we discuss a dedicated test for dipole radiation due to a massive field using the LIGO/Virgo collaboration's open data. In addition, assuming Einstein dilaton Gauss Bonnet (EdGB) type coupling, we combine the results of the analysis of binary black hole events to obtain 90% confidence level constraints on the coupling parameter alpha(EdGB) as root alpha(EdGB) less than or similar to 2.47 km for any mass less than 6 x 10(-14) eV for the first time, including root alpha(EdGB) less than or similar to 1.85 km in the massless limit.
