Abstract

The Bargmann-Wigner (BW) scalar product is a particular case of a larger class of scalar products parametrized by a family of world-vectors. The choice of null and p-dependent world-vectors leads to BW amplitudes which behave as local SU(2) spinors (BW-spinors) if \it passive\/ transformations are concerned. The choice of null directions leads to a simplified formalism which allows for an application of ordinary, manifestly covariant spinor techniques in the context of infinite dimensional unitary representations of the Poincaré group.
