The potential of the HAWC Observatory to observe violations of Lorentz Invariance

Understand

The framework of relativistic quantum-field theories requires Lorentz Invariance.

• Many theories of quantum gravity, on the other hand, include violations of Lorentz Invariance at small scales and high energies.
• This generates a lot of interest in establishing limits on such effects, and, if possible, observing them directly.
• Gamma-ray observatories provide a tool to probe parts of the parameter space of models of Lorentz Invariance Violation that is not accessible in terrestrial laboratories and man-made accelerators.
