This Mexican physicist has found with, Fortin, and Stergiou an important result on Quantum Field Theories, [link].

Non-trivial behavior in charge space, for theories near a scale invariant fixed point.

This could be related with the general behavior of cross sections observed experimentally since the late sixties.

The physics lore that limit cycles and ergodicity imply perpetual oscillations in the scattering cross
sections is thus correct [15]. The scattering cross sections σ (s) in terms of the center-of-mass energy s
oscillate, i.e., s σ (s) = c(s) for a periodic or quasi-periodic function c(s). The scattering cross sections obey
the standard scaling law, with c(s) a constant, only for theories approaching conformal fixed points."
