Phys. Rev. D 64, 014018 (2001) [18 pages]Spiral multicomponent structure in Padé-approximant QCDReceived 8 November 2000; revised 22 March 2001; published 31 May 2001 We present a numerical method of investigating the infrared structure of Padé-approximant QCD. The investigation shows a triple couplant multiplicity structure (a1,a2,a3) present in all flavor states 0<~Nf<~16, as well as two couplant bifurcation points at two critical momenta Qmin and Qmax. The nature and interpretation of these structures is discussed and related to some earlier findings by other methods. © 2001 The American Physical Society URL:
