Time-Delay And Doppler Tests Of The Lorentz Symmetry Of Gravity, Quentin G. Bailey
Time-Delay And Doppler Tests Of The Lorentz Symmetry Of Gravity, Quentin G. Bailey
Physics & Astronomy - Prescott
Modifications to the classic time-delay effect and Doppler shift in general relativity (GR) are studied in the context of the Lorentz-violating standard-model extension (SME). We derive the leading Lorentz- violating corrections to the time-delay and Doppler shift signals, for a light ray passing near a massive body. It is demonstrated that anisotropic coefficients for Lorentz violation control a time-dependent behavior of these signals that is qualitatively different from the conventional case in GR. Estimates of sensitivities to gravity-sector coefficients in the SME are given for current and future experiments, including the recent Cassini solar conjunction experiment.
