Asymptotic structure of perturbative series for \(\tau\) lepton decay observables: \(m_s^2\) corrections
- 31 Downloads
In a previous paper  we performed an analysis of the asymptotic structure of the perturbation theory series for semileptonic \(\tau\) lepton decays in the massless limit. We extend our analysis to the Cabibbo suppressed \(\Delta S=1\) decay modes of the \(\tau\) lepton. In particular we address the problem of \(m_s^2\) corrections to the theoretical formulas. The properties of the asymptotic behavior of the finite order perturbation theory series for the coefficient functions of the \(m_s^2\) corrections are studied.
