The Homogeneous Lorentz Group,In this Chapter we consider the general properties of the homogeneous Lorentztransformations.We concentrate here on their group theoretical aspects, which give insight into the central role played by special relativity in the description of the elementary particle physics.

One Particle and Two Particle States,Also the states of a massive particle can then be labelled by the helicity eigenvalues.While Lorentz transformations mix different helicity states, rotations leave helicity invariant

Relativistic Equations,which defines the wave function in the configuration space, satisfies the Klein- Gordon equation in the coordinate representation
