One possibility of searching for physics beyond the Standard Model and General Relativity is to conceive experiments capable of detecting possible minuscule violations of Lorentz symmetry. Since such violations were demonstrated to occur in particular string field theories [1,2] as well as in loop quantum gravity [3], tests of Lorentz invariance provide a window into Planck scale physics, which makes this field one of the central thrusts of high-energy physics in the 21st century
The latter is a comprehensive effective field theory framework that parametrizes all deviations from Lorentz invariance that are scalars under coordinate transformations and respect the gauge structure of the Standard Model
