We show that CP-violation can lead to an asymmetric diffusion of the Chern-Simons number in thermal equilibrium. This asymmetry leads to a linearly growing expectation value of the third power of the Chern-Simons number. In the long-time limit all expectation values of powers of Chern-Simon numbers are determined by their appropriate disconnected parts.

The paper
Original abstract
We show that CP-violation can lead to an asymmetric diffusion of the Chern-Simons number in thermal equilibrium. This asymmetry leads to a linearly growing expectation value of the third power of the Chern-Simons number. In the long-time limit all expectation values of powers of Chern-Simon numbers are determined by their appropriate disconnected parts.

It is argued that this asymmetry manifests itself through a linear growth of the expectation value of the third power of the Chern-Simons number.

It is also worth noting that CP-violating effects in the sphaleron sector do not shift the equilibrium point away from $n_ = 0$ [ref] .
