We study the link between relaxation to the equilibrium and anomaloussuperdiffusive motion in a classical N-body hamiltonian system with long-rangeinteraction showing a second-order phase-transition in the canonical ensemble.Anomalous diffusion is observed only in a transient out-of-equilibrium regimeand for a small range of energy, below the critical one. Superdiffusion is dueto L\'evy walks of single particles and is checked independently through thesecond moment of the distribution, power spectra, trapping and walking timeprobabilities. Diffusion becomes normal at equilibrium, after a relaxation timewhich diverges with N.Comment: 5 pages, 4 postscript figures included, revtex, revised version refs.  and a few sentences added, fig.3 revised, typos corrected.
