Description
The use of covariant formalisms in amplitude analysis is becoming more and more popular among the experimental collaborations. We discuss some of the tensor formalisms available in the literature, and check whether or not they satisfy the $S$-matrix constraints. We match these to the usual helicity amplitudes, showing that there is no need for "relativistic" corrections.
