Manifestly covariant formalism for Bargmann-Wigner fields is developed.
It is shown that there exists some freedom in the choice of the form of the Bargmann-Wigner scalar product: The general product depends implicitly on a family of world-vectors. The standard choice of the product corresponds to timelike and equal vectors which define a ``time" direction. The generalized form shows that formulas are simpler if one chooses {\it null\/} directions. This freedom is used to derive simple…
