✦ Synopsis

The collinear singularity problem of hot QCD is revisited within a perturbative resummation scheme (PR) of the leading thermal fluctuations. On the basis of actual calculations, new aspects are discovered concerning the origin of the singularity plaguing the soft real photon emission rate out of a quark-gluon plasma at thermal equilibrium, when the latter is calculated by means of the Resummation Program (RP).

The problem presented in this paper is a model related to the collinear three-body problem which is itself a special case of the full three-body problem where three point masses interact under inverse square gravitation. The three-body problem has been known since Newton to be notoriously difficult.
