Progress on symmetry breaking and generational mixing in topcolor-assisted technicolor [PDF]
, 1996 Topcolor-assisted technicolor provides a dynamical explanation for electroweak and flavor symmetry breaking and for the large mass of the top quark without unnatural fine tuning.

, 2005 We propose a scenario of dynamical electroweak symmetry breaking which is applicable to the model with no tree-level potential for the elementary Higgs doublet field. An example of such a model is the gauge-Higgs unification model. The strong coupling "technicolor" dynamics can provide the scale of the electroweak symmetry breaking in the potential of ...

Gauge-Assisted Technicolor? [PDF]
Journal of High Energy Physics, 2004 It is well known that technicolor models in which the electroweak symmetry is broken by QCD-like strong dynamics at the TeV scale generally predict unacceptably large corrections to low-energy observables. We investigate the models of electroweak symmetry breaking by strong dynamics in which the gauge symmetry is extended to include an arbitrary number

Precision tests of technicolor
Physics Letters B, 1992 Abstract Corrections to the standard electroweak model are computed within the framework of technicolor theories. Special attention is paid to new variants of these theories involving high momentum enhancement, developed during the past few years. It is argued that for a reasonable range of the parameters entering the theories, deviations from the ...

Probing Near-Conformal Technicolor through Weak Boson Scattering
, 2012 The recently observed boson at 125 GeV could be a light composite scalar from near-conformal technicolor dynamics: a technicolor Higgs. If this is the case, unitarization of longitudinal weak boson scattering amplitudes, which is due to exchanges of the ...

Strong and Weak CP Violation in Technicolor [PDF]
, 2001 I discuss vacuum alignment and CP violation in technicolor theories of electroweak and flavor symmetry breaking. I review the surprising appearance of rational phase solutions in the technifermion sector and propose a new solution of the strong CP ...

Discovering technicolor at hadron colliders [PDF]
, 1996 Strategies are presented for discovering light, color-singlet technipions (pi_T) produced in association with a vector boson through s-channel technirho production, at the Tevatron and LHC. Signal and W+jets background were simulated including detector effects.

Strong Electroweak Symmetry Breaking
, 2011 Models of spontaneous breaking of electroweak symmetry by a strong interaction do not have fine tuning/hierarchy problem. They are conceptually elegant and use the only mechanism of spontaneous breaking of a gauge symmetry that is known to occur in ...

On the Unification of Gauge Symmetries in Theories with Dynamical Symmetry Breaking
, 2005 We analyze approaches to the partial or complete unification of gauge symmetries in theories with dynamical symmetry breaking. Several types of models are considered, including those that (i) involve sufficient unification to quantize electric charge ...

Physics Letters B, 1987 Abstract We propose an ETC model based on SO(10) 2 which naturally accomodates a complete family of technifermions in the 7 of SO(7) TC plus three generations of quarks and leptons. The technicolor sector corresponds to one of the examples recently shown by Appelquist et al. to avoid the flavor-changing neutral-current problem. In order to obtain
