Generalized Unitarity Method for Worldline Field Theory
Vincent F. He, Julio Parra-Martinez
We present a generalized unitarity method for theories of point-particle worldlines coupled to gravity, analogous to that of scattering amplitudes in quantum field theory. This met…

Measuring Gravitational Wave Speed and Lorentz Violation with the First Three Gravitational-Wave Catalogs
Anarya Ray, Pinchen Fan, Vincent F. He +4
The speed of gravitational waves can be measured with the time delay between gravitational-wave detectors. Our study provides a more precise measurement of using gravit…
