| Abstract: | We present a new version the procedure for calculation helicity amplitudes with massive particles. First, we introduce a massive 4-momentum into higher dimensional space, where it can be treated as massless. Secondly, we apply the symmetry properties of gauge theories and get quite simple matrix elements in terms of the field strength. |
