Modern Tests of Spacetime Symmetry
Lorentz symmetry, a foundational principle in both the Standard Model of
particle physics and general relativity, is challenged by certain quantum
gravity models that predict possible violation. Detecting these tiny Lorentz
symmetry violation, or Lorentz violation, has become a global scientific
interest, with interference experiments and other precise systems offering
the sensitivity needed for such tests. Neutrino oscillations, which act as
natural interferometers, provide an ideal framework for investigating Lorentz
violation.
In this talk, I will begin by introducing Lorentz violation and the
theoretical framework to look for Lorentz violation, known as the Standard
Model Extension (SME). Then I highlight key experiments—from tabletop setups
to cosmological observations—designed to detect Lorentz violation. I will
discuss Lorentz violating neutrino oscillations that might explain existing
data anomalies and conclude with prospects for one of the most precise
Lorentz symmetry tests using astrophysical high-energy neutrinos at neutrino
telescopes.
