|The introduction of a "step scaling method" at finite
volume allows the extraction, in the continuum limit
of Lattice QCD (quenched approximation), of physical
quantities related to heavy flavours (f_B, m_b), whitout
the needs of effective theories and/or lagrangians. The
method could be extended to any problem involving two
widely separated energy scales, and hopefully opens the
way to the lattice computation of heavy flavours physics
in the full theory.
