Improved Bounds on Lorentz Symmetry Violation from High-Energy Astrophysical Sources

Key Points

The aim is to establish more precise limits on Lorentz violation in the electron sector using high-energy astrophysical observations.
Analyzed synchrotron and inverse Compton emissions from ultrarelativistic electrons in astrophysical sources.
Utilized 𝛾-ray telescope data to evaluate energy-momentum relations of electrons.
Constrained lorentz-violating parameters of electrons based on observational data.
Achieved bounds on lorentz-violating parameters at a precision level of 7×10−16 or better.
Confirmed the usefulness of astrophysical sources in probing fundamental symmetries in physics.

Abstract

Observations of the synchrotron and inverse Compton emissions from ultrarelativistic electrons in astrophysical sources can reveal a great deal about the energy–momentum relations of those electrons. They can thus be used to place bounds on the possibility of Lorentz violation in the electron sector. Recent 𝛾 -ray telescope data allow the Lorentz-violating electron 𝑐𝜈𝜇 parameters to be constrained extremely well, so that all bounds are at the level of 7×10−16 or better.
