Description
The Bargmann-Wigner procedure for constructions spin-1 and spin-3/2 fields are well described in the textbooks. We modify this procedure based mainly on the motivations of the ideas of dual electrodynamics and the possibility of the QFT construct with the bosons of opposite parities, and the necessity to have the causal behaviour of the corresponding particles (even in the presence of external fields) . Next, we proceed to derive equations for the symmetric tensor of the second rank on the basis of the Bargmann-Wigner formalism in a straightforward way. The symmetric multispinor of the fourth rank is used. It is constructed out of the Dirac 4-spinors. Due to serious problems with the interpretation of the results obtained on using the standard procedure we generalize it and obtain the spin-2 relativistic equations, which are consistent with those given before. The importance of the 4-vector field (and its gauge part) is pointed out.
