On the Helicity Sign

Authors: Clemens Heuson

Massless angle and square spinors are described together using an index corresponding to their helicity sign. This can be applied to massive spinors as well. Relations between spinors can be written more compactly and some derivations are simplified. Massless polarisation vectors of different helicities can be treated together with this index. Three point and some higher point amplitudes are investigated within this ansatz and recursion with massless spinors is considered.
