Fixed point structure of Pade-summation approximations to the QCD beta-function

V. Elias, F. Chishtie, T. G. Steele

Padé-improvement of four-loop beta-functions in massive phi^4 scalar field theory is shown to predict the known five-loop contribution with astonishing (0.2%) accuracy, supporting…

Compatibility of $α_{s} (M_{τ})$ with $α_{s} (M_{Z})$

T. G. Steele, V. Elias

The current phenomenological determinations of $α_{s} (M_{τ})$ and $α_{s} (M_{Z})$ are shown to be only marginally consistent with the QCD evolution of the strong coupling constant between $…
