TLDR
In this article, a theory consisting of massless Fermi and vector-meson fields can lead to an excitation spectrum of solely massive particles, and a detailed model is presented and solved in lowest order.Abstract:
We demonstrate how a theory consisting of massless Fermi and vector-meson fields can lead to an excitation spectrum of solely massive particles. We eschew spinless Bose fields in the fundamental Lagrangian, contrary to current practice. A detailed model is presented and solved in lowest order. Fermion and axial-vector-meson masses are spontaneously generated, and the vector particle's mass is computed in terms of the fermion mass.read more

Strong dynamics and electroweak symmetry breaking
TL;DR: The breaking of electroweak symmetry, and origin of the associated "weak scale" vweak = 1/ q 2 √ 2GF = 175 GeV, may be due to a new strong interaction as mentioned in this paper.

Exact renormalization group equations. An Introductory review
C. Bagnuls,C. Bervillier +1 more
TL;DR: The use of the exact renormalization group equations (ERGE) in the framework of scalar theory is discussed in this article, where the authors focus on the existence of different versions of the ERGE and on an approximation method to solve it.

Pion mass and decay constant
TL;DR: In this paper, the pion Bethe-Salpeter amplitude and the quark propagator in the chiral limit were derived and the axial-vector Ward-Takahashi identity was preserved.

Dynamical electroweak symmetry breaking with large anomalous dimension and t quark condensate
TL;DR: In this paper, a new class of models with dynamical electroweak symmetry breaking is proposed, where the composite operator ψ ψ has a large anomalous dimension γm≅2 and the t quark plays an important role in the generation of W and Z boson masses.
