Dynamical chiral-symmetry breaking in asymptotically free theories with a slowly running coupling is analyzed. When the confinement scale ..lambda.. is much less than the cutoff M beyond which the theory cannot be used in isolation, the dynamical mass ..sigma..(p) starts from a value approx. =..lambda.. for momenta papprox. ..lambda... It then takes on the asymptotic form (lnp)/sup a//p/sup 2/ where a>1. In hypercolor theories this behavior generates sufficiently large fermion masses for a… 

Running coupling in the conformal window of large-Nf QCD

A bstractQuantum Chromodynamics with a relatively large number of fundamentally charged quark flavours in the chiral limit is considered. A self-consistent solution of the quark, gluon and ghost

Infrared regime of SU(2) with one adjoint Dirac flavor

SU(2) gauge theory with one Dirac flavor in the adjoint representation is investigated on a lattice. Initial results for the gluonic and mesonic spectrum, static potential from Wilson and Polyakov

Nonperturbative β function of eight-flavor SU(3) gauge theory

A bstractWe present a new lattice study of the discrete β function for SU(3) gauge theory with Nf = 8 massless flavors of fermions in the fundamental representation. Using the gradient flow running

Lattice Study on quantum-mechanical dynamics of two-color QCD with six light flavors

We investigate the chiral properties of SU(2)C gauge theory with six flavors, i.e. six light Dirac fermions in the fundamental representations by lattice simulation, and point out that the
