We propose an all orders beta function for ordinary Yang-Mills theories with or without fermions inspired by the Novikov-Shifman-Vainshtein-Zakharov beta function of N=1 supersymmetric gauge theories. The beta function allows us to bound the conformal window. When restricting to one adjoint Weyl fermion we show how the proposed beta function matches the one of supersymmetric Yang-Mills theory. The running of the pure Yang-Mills coupling is computed and the deviation from the two loop result is…

Nonperturbative infrared fixed point in sextet QCD

The SU(3) gauge theory with fermions in the sextet representation is one of several theories of interest for technicolor models. We have carried out a Schrodinger functional (SF) calculation for the

Chiral hierarchies and flavor-changing neutral currents in hypercolor.

Dynamical chiral-symmetry breaking in asymptotically free theories with a slowly running coupling is analyzed, finding that in hypercolor theories this behavior generates sufficiently large fermion masses for a higher value of M than naively expected.
