Instanton Triggered Chiral Symmetry Breaking, the U(1) Problem and a Possible Solution to the Strong CP Problem
William A. Bardeen
We argue that instantons play a crucial role in triggering the spontaneous breaking of chiral symmetry in the physics of the three light quarks in quantum chromodynamics. However,…
Light Dark Matter, Naturalness, and the Radiative Origin of the Electroweak Scale
Wolfgang Altmannshofer, William A. Bardeen, Martin Bauer +2
We study classically scale invariant models in which the Standard Model Higgs mass term is replaced in the Lagrangian by a Higgs portal coupling to a complex scalar field of a dark…
The Massive Fermion Phase for the U(N) Chern-Simons Gauge Theory in D=3 at Large N
William A. Bardeen
We explore the phase structure of fermions in the U(N) Chern-Simons gauge theory in three dimensions using the large N limit where N is the number of colors and the fermions are ta…
Spontaneous Breaking of Scale Invariance in a d=3 U(N) Model with Chern-Simons Gauge Field
William A. Bardeen, Moshe Moshe
We study spontaneous breaking of scale invariance in the large N limit of three dimensional Chern-Simons theories coupled to a scalar field in the fundamental representati…
Large N Approach to Kaon Decays and Mixing 28 Years Later: Delta I = 1/2 Rule, \hat B_K and Delta M_K
Andrzej J. Buras, Jean-Marc Gerard, William A. Bardeen
We review and update our results for K-> pipi decays and K^0-\bar K^0 mixing obtained by us in the 1980s within an approach based on the dual representation of QCD as a theory of w…
Weak Mixing and Rare Decays in the Littlest Higgs Model
William A. Bardeen
Little Higgs Models have been introduced to resolve the fine-tuning problems associated with the stability of the electroweak scale and the constraints imposed by the precision ele…
