Abstract
In a previous paper [1]
we performed an analysis of
the asymptotic structure of the perturbation theory series for
semileptonic
lepton decays in the massless limit.
We extend our analysis
to the Cabibbo suppressed
decay modes of the
lepton. In particular
we address the problem of ms2 corrections
to the theoretical formulas. The
properties of
the asymptotic behavior of the finite order perturbation theory
series
for the coefficient functions of the ms2 corrections
are studied.
