Lorentz invariance is a part of Einstein’s theory of special relativity which is the foundation of some of the technologies that we use every day, for example the GPS.

A breaking of the Lorentz invariance is obtained by adding a Lorentz violation term to a Lorentz invariant Lagrangian. In the standard model this results in 46 real parameters which are independent Lorentz violations, but they preserve the anomaly cancellation that is required, without setting any extra constraints on the parameters. By looking at the difference of the maximal attainable velocity of elementary particles decaying, it is shown that the difference in these velocities is of the order of 10−21, and thereby very small.
