  We study the Kelvinons: monopole ring solutions to the Euler equations,
regularized as the Burgers vortex in the viscous core. There is finite
anomalous dissipation in the inviscid limit. However, in the anomalous
Hamiltonian, some terms are growing as logarithms of Reynolds number; these
terms come from the core of the Burgers vortex. In our theory, the turbulent
multifractal phenomenon is similar to asymptotic freedom in QCD, with these
logarithmic terms summed up by an RG equation. The small effective coupling
does not imply small velocity; on the contrary, velocity is large compared to
its fluctuations, which opens the way for a quantitative theory.
  In the leading order in the perturbation theory in this effective coupling
constant, we compute running multifractal dimensions for high moments of
velocity circulation, in good agreement with the data for quantum Turbulence
and available data for classical Turbulence. The logarithmic dependence of
fractal dimensions on the loop size comes from the running coupling in
anomalous dimensions. This slow logarithmic drift of fractal dimensions would
be barely observable at Reynolds numbers achievable at modern DNS.
