Real time effective theory in a hot gauge theory with a Z(N) interface
Seminar Room 1, Newton Institute
We explore real time phenomena such as plasma oscillations and Debye screening in a SU(N) gauge theory with a Z(N) interface at high temperature, where the Z(N) symmetry is spontaneously broken. The Z(N)interface is obtained as a solution between different Z(N) vacua. In the background we show that gluons and quarks have unusual distributions, and gluon mass and Debye screening mass are changed. We construct a real-time effective theory in the background.
