Slavnov-Taylor identity for nonequilibrium quark-gluon plasma
Kaoru Okano
Within the closed-time-path formalism of nonequilibrium QCD, we derive a Slavnov-Taylor (ST) identity for the gluon polarization tensor. The ST identity takes the same form both in…

Reaction-rate formula in out of equilibrium quantum field theory
A. Niegawa, K. Okano, H. Ozaki
A complete derivation, from first principles, of the reaction-rate formula for a generic reaction taking place in an out of equilibrium quantum-field system is given. It is shown t…

A Slavnov-Taylor identity and equality of damping rates for static transverse and longitudinal gluons in hot QCD
M. Dirks, A. Niegawa, K. Okano
A Slavnov-Taylor identity is derived for the gluon polarization tensor in hot QCD. We evaluate its implications for damping of gluonic modes in the plasma. Applying the identity to…
