Search for Dynamical Symmetry Breaking Physics by Using Top Quark ∗
We report first results from the investigation on probing dynamical mechanism of the electroweak symmetry breaking using top quark. We consider the case where the top mass originates from a fermion-antifermion pair con-densate, which necessitates (i)strong interaction to cause condensation, and (ii)4-fermi interaction to give top mass. From the observed top mass and the unitarity constraint, we...
متن کاملDynamical Electroweak Symmetry Breaking and the Top Quark∗
In this talk I discuss theories of dynamical electroweak symmetry breaking, with emphasis on the implications of a heavy top-quark on the weak-interaction ρ parameter. ∗AN ABBREVIATED VERSION OF THIS TALK WAS PRESENTED AT THE WORKSHOP ON TOP QUARK PHYSICS, IOWA STATE UNIVERSITY, AMES, IA, MAY 25-26, 1995 AND THE YUKAWA INTERNATIONAL SEMINAR ‘95, YUKAWA INSTITUTE, KYOTO, AUG. 21-25, 1995. 1 What...
متن کاملSymmetry Breaking Involving the Top Quark
In models of dynamical electroweak symmetry breaking which sensitively involve the third generation, such as top quark condensation, the effects of the new dynamics can show up experimentally in Z → bb. We compare the sensitivity of Z → bb and top quark production at the Tevatron to models of the new physics. Z → bb is a relatively more sensitive probe to new strongly coupled U(1) gauge bosons,...
متن کاملIsospin Breaking and the Top-quark Mass in Models of Dynamical Electroweak Symmetry Breaking∗
In this talk we review the physics of top-quark mass generation in models of dynamical electroweak symmetry breaking and the constraints on this physics arising from limits on the deviation of the weak interaction ρ-parameter from one. We then discuss top-color assisted technicolor in this context. 1. mt in Models of Dynamical Electroweak Symmetry Breaking In technicolor models, the masses of t...
متن کاملTop Mass and Isospin Breaking in Dynamical Symmetry Breaking Scenario
We consider a scenario where the top-quark mass is generated dynamically, and study the implication of the present experimental values for mt and the T parameter. We assume technicolor-like scenario for inducing the W mass and an effective four fermi operator for inducing the top-quark mass. We also assume that only this four fermi operator is relevant at low energy. Then we estimate in detail ...
