Abstract Taking into account gauge conditions, the authors have extended to the massless case results previously obtained (see ibid. vol.7A no.1., 185-225) for massive particles by using Raynal's method. This procedure allowed them to build in the massless case regularized helicity amplitudes the constraints of which have been explicitly derived. (10 refs).
