The term "Lorentz invariant" almost always actually means "Lorentz covariant", where "covariant" is understood as meaning certain things for certain types of objects (tensors). For example, if ϕ(x) ϕ ( x) is a Lorentz scalar, then if you change coordinates from x x to y(x) y ( x), you will find ϕ(y(x)) = ϕ(x) ϕ ( y ( x)) = ϕ ( x), i.e ... A comparison of this equation with ( 1153) reveals that the Dirac equation takes the same form in frames and . In other words, the Dirac equation is Lorentz invariant. Incidentally, it is clear from ( 1153) and ( 1159) that the matrices are the same in all inertial frames. It remains to find a transformation matrix that satisfies ( 1158 ).For a Lorentz transformation we have. mστ ↔ δxμ = ϵ(gμσxτ −gμτxσ) (notice that this is antisymmetric and so there are just 6 independent parameters of the transformation) and so the conserved currents are the angular momentum currents.
