The breaking of electroweak symmetry, and origin of the associated “weak scale”, v weak=
1/2 2 GF= 175 GeV, may be due to a new strong interaction. Theoretical developments over …

Two-component spinors are the basic ingredients for describing fermions in quantum field
theory in 3+ 1 spacetime dimensions. We develop and review the techniques of the two …

The Pythia program can be used to generate high-energy-physicsevents', ie sets of outgoing
particles produced in the interactions between two incoming particles. The objective is to …

We formulate the dynamical symmetry breaking of the standard model by a top-quark
condensate in analogy with BCS theory. The low-energy effective Lagrangian is the usual …

We develop an effective field theory of QCD and QCD-like theories beyond the Standard
Model, based on the hidden local symmetry (HLS) model for the pseudoscalar mesons (π) …

We describe a color embedding, SU (3) c→ SU (3) 1× SU (3) 2, that is designed to break
electroweak symmetries through top quark condensation. The minimal scheme of Bardeen …

We study a left--right symmetric model which contains only elementary gauge boson and
fermion fields and no scalars. The phenomenologically required symmetry breaking …

We study the phase diagram as a function of the number of colors and flavors of
asymptotically free nonsupersymmetric theories with matter in higher-dimensional …

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 study left-right symmetric models which contain only fermion and gauge boson fields
and no elementary scalars. The Higgs bosons are generated dynamically through a set of …
