Query: One-loop photon-photon scattering in a thermal, deconfining SU(2)
  Yang-Mills plasma   For a deconfining thermal SU(2) Yang-Mills plasma we discuss the role of
(anti)calorons in introducing non-thermal behavior effectively described in
terms of Planck's quantum of action $\hbar$. This non-thermality cancels
exactly between the ground-state estimate and its free quasiparticle
excitations. Kinematic constraints in 4-vertex scattering and the counting of
radial loop variables versus the number of independent constraints on them are
re-visited. Next, we consider thermal 2$\rightarrow$ 2 one-loop scattering of
the modes remaining massless upon the (anti)caloron induced adjoint Higgs
mechanism (thermal ground state after spatial coarse graining). Starting with
stringent analytical arguments, we are able to exclude the contribution to
photon-photon scattering from diagrams containing at least one three-vertex
and, in a next step, a vast majority of all possible configurations involving
two four-vertices. By numerical analysis we show that the remaining
contribution of the overall S channel is severely suppressed compared to that
of the T and U channels, meaning that the creation of a pair of massive vector
modes by a pair of photons and vice versa practically does not occur in the
Yang-Mills plasma. For the T and U channels the domain of loop integration
represents less than $10^{-7}$ times the volume of the unconstrained
integration region. The thus introduced photon-photon correlation should affect
the Cosmic Microwave Background's polarisation at low redshift. An adaption of
the here-developed methods to the analysis of irreducible bubble diagrams could
prove the conjecture of hep-th/0609033 on the termination of the loop expansion
of thermodynamical quantities at a finite irreducible order.
