Non-transversality of the gluon polarization tensor in a chromomagnetic background
Abstract
We investigate the question about the transversality of the gluon polarization tensor in a homogeneous chromomagnetic background field. We re-derive the non transversality known from a pure one loop calculation using the Slavnov-Taylor identities. In addition we generalize the procedure to arbitrary gauge fixing parameter and calculate the -dependent part of the polarization tensor.
