Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

We review the theoretical developments and conceptual advances that stemmed from the
generalization of QCD to the limit of a large number of color charges, originally proposed by't …

We consider examples of “hidden-valley” models, in which a new confining gauge group is
added to the standard model. Such models often arise in string constructions, and …

We show that it is possible to construct explicit models of electroweak symmetry breaking in
which the number of techniflavors needed to enter the conformal phase of the theory is small …

We investigate theories in which the technifermions in higher dimensional representations of
the technicolor gauge group dynamically break the electroweak symmetry of the standard …

We introduce the topic of dynamical breaking of the electroweak symmetry and its link to
unparticle physics and cosmology. The knowledge of the phase diagram of strongly coupled …

A bstract We study the dynamics of four dimensional gauge theories with adjoint fermions for
all gauge groups, both in perturbation theory and non-perturbatively, by using circle …

We investigate new models of dynamical electroweak symmetry breaking resulting from the
condensation of fermions in higher representations of the technicolor group. These models …

We discuss the lattice formulation of gauge theories with fermions in arbitrary
representations of the color group and present in detail the implementation of the hybrid …

We construct an anomaly-preserving compactification of 4D gauge theories, including SU
(N) Yang–Mills theory, supersymmetric Yang–Mills theory, and quantum chromodynamics …
