In this paper the configurational entropy of the energy-energy correlation function is scrutinized, in e+e− collisions to hadrons in the back-to-back region, within the QCD perturbative theory. The critical points of the configurational entropy concept, in the hot nuclear system, is shown to correspond to the critical angle between the two scattered hadrons, corroborating this with phenomenological data with great accuracy. The main tools employ the main coefficients of the soft-gluon resummation formula, taking into account logarithmically enhanced contributions up to next-to-next-to-leading logarithmic accuracy.
