Higher Dimensional Operators in Top Condensation from a Renormalization Group Point of View
Andreas Blumhofer, Richard Dawid, Johannes Manus
The predictive power of top-condensation models strongly depends on the behaviour of higher dimensional operators. These are analyzed in this paper by an extension of the standard…
New Insight in Dynamical Symmetry Breaking via Imaginary Part Analysis
Andreas Blumhofer, Johannes Manus
We present a new method solving Schwinger-Dyson equations in gauge theories via imaginary part analysis. The self-consistency equation for the fermion self-energy can be reduced fr…
Family Structure from Periodic Solutions of an Improved Gap Equation
Andreas Blumhofer, Marcus Hutter
Fermion mass models usually contain a horizontal symmetry and therefore fail to predict the exponential mass spectrum of the Standard Model in a natural way. In dynamical symmetry…
Connections between Dynamical and Renormalization Group Techniques in Top Condensation Models
Andreas Blumhofer, Richard Dawid, Manfred Lindner
Predictions for the ratio arise in top condensation models from different methods. One type of prediction stems from Pagels--Stokar relations based on the use of Ward Ide…
Exact Cancellation of Quadratic Divergences in Top Condensation Models
Andreas Blumhofer
We discuss the hierarchy problem and the corresponding quadratic divergences in the top mode Standard Model. Quadratic divergences appear at each order 1/N_c since fermionic and bo…
Top Condensation without Fine-Tuning
Andreas Blumhofer
Quadratic divergencies which lead to the usual fine-tuning or hierarchy problem are discussed in top condensation models. As in the Standard Model a cancellation of quadratic diver…
