Some results on the general axial gauge in quantum gravity

Abstract

Commenting on a previous paper, we present two further results on the general axial gauge in quantum gravity: (i) We are now able to give the infinite part of the complete graviton self-energy ${\ensuremath{\pi}}_{\ensuremath{\mu}\ensuremath{\nu},\ensuremath{\rho}\ensuremath{\sigma}}$ in the axial gauge, rather than its corresponding scalar amplitudes. (ii) We present results for more general axial gauges and show that for any value of the gauge parameter the infinite part of the graviton self-energy remains nontransverse and ${n}_{\ensuremath{\mu}}$ dependent.
