[37–42]). The effects of local Lorentz violation on dispersion and birefringence of gravitational waves are investigated.

1 The Dirac field and Lorentz invariance Much of the content of this section is in Peskin and Schroeder, Sections 3.1 and 3.2. You should study these sections. Among the finite dimensional representations of the Lorentz group that we have found is the (1/2,0)⊕(0,1/2) representation. The objects on which

Intervals can be positive (space-like), Lorentz covariance, a related concept, is a property of the underlying spacetime manifold. Lorentz covariance has two distinct, but closely related meanings: A physical quantity is said to be Lorentz covariant if it transforms under a given representation of the Lorentz group. According to the representation theory of the Lorentz group, these quantities are built out of scalars, four-vectors, four-tensors, and spinors. In particular, a Lorentz covariant scalar remains the same under Lorentz tran 0c2 is a Lorentz invariant quantity.

Lorentz invariance expresses the proposition that the laws of physics are the same for different observers, for example, an observer at rest on Earth or one who is rotated through some angle, or traveling at a constant speed relative to the observer at rest.

General relativity includes the invariance through Einstein’s equivalence principle, which implies that any experiment conducted in a small, freely falling laboratory is invariant under Lorentz transformations. That result is known as local Lorentz invariance. Motivated by ideas about quantum gravity, a tremendous amount of effort over the past decade has gone into testing Lorentz invariance in various regimes.

802-822. Rabounski, D. If Lorentz invariance were violated, the gamma rays would pass right through the extragalactic infrared fog without being annihilated. This is because annihilation requires a certain amount of energy in order to create the electrons and positrons.
