Phase Transition Critical Flavor Number of QCD
Abstract
We present an entirely perturbative QCD determination of the critical phase transition flavor number Ncrf of QCD. The results obtained are compared with various determinations of Ncrf by non-pertrubative methods, including lattice QCD. The wider physics implication of the existence of the Banks-Zaks regime of QCD with only weakly interacting quarks, is discussed briefly.
