Scientific paper

In the framework of the low energy Chiral Lagrangian, the renormalization
group equations for the couplings are investigated up to order p^6, both for
the SU(2) as for the SU(3) cases. Infrared attractive fixed points for ratios
of couplings are found. These fixed points solutions turn out to agree with the
values determined from experiment in a large number of cases.
