Massive Fields with Arbitrary Integer Spin in Homogeneous Electromagnetic Field

Abstract

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 vectors in 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 of spin $s$ in terms of symmetrical tensor fields in linear approximation. The result obtained does not depend on dimensionality of space-time.
