Topcolor Assisted Technicolor Models

چکیده
We consider the lepton-flavor violating(LFV) processes li → ljγ in the framework of topcolor assisted technicolor(TC2) models. We find that the new gauge boson Z ′ predicted by TC2 models can give significantly contributions to these processes via the flavor changing couplings. The present experimental bound on the LFV process μ → eγ gives severe constraints on the TC2 models. In the case that the Z ′ mass MZ is consistent with other experimental constraints, we obtain constraints on the lepton mixing factors Kτμ and Kτe. The future LFV experiments will be probe of the TC2 models.

Top Decay in Topcolor-Assisted Technicolor
Conventional technicolor models with light charged technipions (π T ) lead to an unacceptably large contribution to t → π T b decay rate. Topcolor-assisted technicolor models also have additional PGBs called top-pions (π t ) which may contribute to this decay. We study the potentially dangerous mixing of charged top-pion and technipions in toy models of ‘natural’ topcolor-assisted technicolor. ...
متن کاملProgress on Symmetry Breaking and Generational Mixing in Topcolor-assisted Technicolor
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. I briefly review the basics of topcolor-assisted technicolor, including major constraints and a general approach to satisfying them. The main challenge to topcolor-assisted technicolor is to generate the observed mixin...
متن کاملTopcolor Assisted Technicolor
A condensate, tt, arising from O(TeV ) scale “topcolor,” in addition to technicolor (and ETC) may naturally explain the gauge hierarchy, the large top quark mass, and contains a rich system of testable consequences. A triplet of strongly coupled pseudo–Nambu–Goldstone bosons, “toppions,” near the top mass scale is a generic prediction of the models. A new class of technicolor schemes and associ...
متن کاملB̄–B Mixing Constrains Topcolor–Assisted Technicolor
We argue that extended technicolor augmented with topcolor requires that all mixing between the third and the first two quark generations resides in the mixing matrix of left–handed down quarks. Then, the B̄d–Bd mixing that occurs in topcolor models constrains the coloron and Z ′ boson masses to be greater than about 5 TeV. This implies fine tuning of the topcolor couplings to better than 1%. bu...
متن کاملTopcolor assisted technicolor models and muon anomalous magnetic moment
We discuss and estimate the contributions of the new particles predicted by topcolor assisted technicolor(TC2) models to the muon anomalous magnetic moment aμ. Our results show that the contributions of Pseudo Goldstone bosons are very small which can be safely ignored. The main contributions come from the ETC gauge boson xμ and topcolor gauge boson Z ′. If we demand that the mass of Z ′ is con...
متن کاملDynamical Computation on Coefficients of Electroweak Chiral Lagrangian from One-doublet and Topcolor-assisted Technicolor Models
Abstract Based on previous studies deriving the chiral Lagrangian for pseudo scalar mesons from the first principle of QCD, we derive the electroweak chiral Lagrangian and build up a formulation for computing its coefficients from one-doublet technicolor model and a schematic topcolor-assisted technicolor model. We find that the coefficients of the electroweak chiral Lagrangian for the topcolor...
