Spiral Multi-component Structure in Pade - Approximant QCD

Abstract

We present a graphical method of analyzing the infra-red fixed point structure of Pade approximant QCD. The analysis shows a spiral multi-component couplant structure as well as an infra-red attractor behavior of PQCD couplant for all flavors $0\le N_f\le 16$.
