Abstract: | A new method is proposed for calculating amplitudes of processes involving spin-1/2 fermions. The method is based on the use of the isotropic-vierbein vectors in Minkowski space and the basis spinors associated with them. The amplitudes for the electron-positron interaction processes e?e+ → ff and e?e+ → W?W+ and the amplitude for one of the possible diagrams for the process e+e? → e+e?e+e?e+e? are calculated in order to test and illustrate the potential of the method. |
