Anomalous Wtb Couplings and b → sγ in the Topcolor Assisted Technicolor Models

Using topcolour-assisted technicolour models, we give the anomalous Wb couplings arising from the exchange of the new gauge bosons (ETC gauge boson, colorons and Z') and calculate their contributions

Rc constrains topcolour-assisted technicolour models

We consider the Z → c branching ratio Rc in the context of topcolour-assisted technicolour (TC2) models. We find that the main corrections to Rc in TC2 models come from the neutral top-pion π0t and

Collider phenomenology of technihadrons in the technicolor straw man model

We discuss the phenomenology of the lightest SU(3)C singlet and non-singlet technihadrons in the Straw Man Model of low-scale technicolor (TCSM). The technihadrons are assumed to be those arising in

Production of the lightest neutral technipion at the First Muon Collider

In the framework of the topcolour-assisted multiscale technicolour (TOPCMTC) models, we discuss the s-channel resonance production of the lightest neutral technipion P0 at the First Muon Collider

Probing Topcolor-Assisted Technicolor Models from Like-Sign τ Pair Production in eγ Collisions

We consider the contributions of the extra gauge boson Z' to the like sign τ production processes e−γ → e+(μ+)τ−τ−, induced by the tree-level flavor changing interactions. Since these rare production

The colour-singlet technipion P0 and the recent experimental results at LEPII

We study the contributions of the technipion P0 predicted by the technicolour theory to the process e+e-→Zb. Our results show that the production cross section σ is very small. The value of the cross



Spontaneously broken technicolor and the dynamics of virtual vector technimesons.

This work proposes spontaneously breaking technicolor, thus liberating techniquarks and suppressing large resonance contributions to the electroweak [ital S] parameter, and proposes a Nambu--Jona-Lasinio model with additional interactions.

Raising the sideways scale

Extended hypercolor theories have been plagued with inherent flavor-changing effects occurring above experimental levels. The problem may be alleviated in a scenario in which hyper-color interactions

A New Problem and the Possible Solution in the Technicoloured Preon Model

A version of technicoloured preon model, giving the appropriate order of fermion mass despite the large mass scale of the preonic dynamics of the order of the axion decay constant, is presented,

Scale-invariant hypercolor model and a dilaton.

A scale-invariant hypercolor model with a nontrivial ultraviolet fixed point having large anomalous dimension is proposed, which resolves the notorious flavor-changing neutral-current problem in hypercolor models and predicts a Nambu-Goldstone boson (dilaton) associated with the spontaneous breakdown of the scale invariance.

This paper discusses the prospects for making a renormalizable version of this ``top bootstrap'' scenario using a strongly coupled spontaneously broken gauge interaction, and argues that these models are somewhat similar to the extended technicolor models, but with a ``technicolor'' force, providing the mass-generation mechanism for the top quark.

CP violation without elementary scalar fields

Dynamically broken gauge theories of electroweak interactions provide a natural mechanism for generating CP violation. Even if all vacuum angles are unobservable, strong CP violation is not
