Relativistic quantum fields can be classified according to the way they transform under Lorentz transformations. More specifically, they transform according to irreducible representations of the Lorentz group. The different representations give rise to particles with different values of the spin angular momentum.
According to the principle of special relativity, the laws of physics should be covariant with respect to Lorentz transformations; that is, they should have the same forms in all reference frames connected by Lorentz transformations. The simplest Lorentz transformation is a "boost" of the reference frame with velocity v along some axis, say, the x axis:
This may be supplemented by a rotation of the coordinate system, say, about the z axis through an angle 8: x' = x cos0 + y sin8 y' = -x sin8 + y C O S ~ Defining a boost "angle" by cosh4 = 1lVl -v 2 sinh4 = v d l -v2 (3.3)
