Bordag, Yu. Grebenyuk, V. Skalozub] We investigate the problem of the transversality of the gluon polarization tensor in a homogeneous Abelian chromomagnetic background field. Using the Slavnov-Taylor identities, we rederive the nontransversality known from a one-loop calculation in the Feynman gauge. In addition, we generalize the whole procedure to an arbitrary gauge-fixing parameter ξ and calculate the ξ-dependent part of the polarization tensor.
