A New Method for Helicity Calculations

Abstract

We propose a new helicity formalism based on the formal insertion in spinor lines of a complete set of states build up with unphysical spinors. The method is developed both for massless and massive fermions for which it turns out to be particularly fast. All relevant formulae are given.
