Massive Fields of Arbitrary Integer Spin in Homogeneous Electromagnetic Field
Protvino, 1998.- p.14, refs.:26.

We study the interaction of gauge fields of arbitrary integer spins with the constant electromagnetic field. We reduce the problem of obtaining the gauge-invariant Lagrangian of integer spin fields in the external field to purely algebraic problem of finding a set of operators with certain features using the representation of the high-spin fields in the form of some vectors on a pseudo-Hilbert space. We consider such a construction up to the second order in the electromagnetic field strength and also present an explicit form of interaction Lagrangian for a massive particle with spin S in terms of symmetrical tensor fields in the linear approximation. The obtained result does not depend on dimensionality of space-time.
