+ One has the following interaction µ¯ µ† → µ¯ µ† where the particles/antiparticles approach and separate along the z-axis and in addition each has initial and final helicity -1. Find the corresponding expressions for the initial and final bi-spinors, of particles and antiparticles The expressions must be a function only of the energies and masses of the particles.
