Gauge invariant accounts of the Higgs mechanism [PDF]

, 2011
The Higgs mechanism gives mass to Yang-Mills gauge bosons. According to the conventional wisdom, this happens through the spontaneous breaking of gauge symmetry.

Tree-level Unitarity in SU 2 L × U 1 Y × U 1 Y ′ $$ \textrm{SU}{(2)}_L\times \textrm{U}{(1)}_Y\times \textrm{U}{(1)}_{Y^{\prime }} $$ Models

Journal of High Energy Physics, 2023
In models with a U(1) gauge extension beyond the Standard Model, one can derive sum rules for the couplings of the theory that are a consequence of tree-level unitarity.

Interactions of particles with “continuous spin” fields

Journal of High Energy Physics, 2023
Powerful general arguments allow only a few families of long-range interactions, exemplified by gauge field theories of electromagnetism and gravity. However, all of these arguments presuppose that massless fields have zero spin scale (Casimir invariant)

Fault-tolerant simulation of Lattice Gauge Theories with gauge covariant codes [PDF]

Quantum
We show in this paper that a strong and easy connection exists between quantum error correction and Lattice Gauge Theories (LGT) by using the Gauge symmetry to construct an efficient error-correcting code for Abelian Z 2 LGTs.

Aspects of spontaneously broken N = 1 global supersymmetry in the presence of gauge interactions [PDF]

, 1997
We discuss models where N=1 global supersymmetry is spontaneously broken, at the classical level, in the presence of non-anomalous gauge interactions.

SU(2) non-Abelian gauge field theory in one dimension on digital quantum computers [PDF]

Physical Review D, 2019
An improved mapping of one-dimensional SU(2) non-Abelian gauge theory onto qubit degrees of freedom is presented. This new mapping allows for a reduced unphysical Hilbert space.

Gauge Mediated Supersymmetry Breaking in Five Dimensions [PDF]

, 2011
PhDIn this thesis we focus on the construction of models in which a supersymmetry breaking hidden sector is located on one fixed point of an extra dimensional interval and the effects are gauge mediated across this interval to the other fixed point ...

Higher-spin gauge interactions for matter fields in two dimensions [PDF]

, 1995
We formulate a new model which describes higher-spin gauge interactions for matter fields in two dimensions. This model is a higher-spin generalization of 2d gravity and turns out to be integrable.

Relevance of induced gauge interactions in decoherence. [PDF]

, 1994
Decoherence in quantum cosmology is shown to occur naturally in the presence of induced geometric gauge interactions associated with particle production.A new 'gauge '-variant form of the semiclassical Einstein equations is also presented which makes the

Nonlinear gauge interactions - A solution to the "measurement problem" in quantum mechanics? [PDF]

, 2000
We propose that the mechanism responsible for the “collapse of the wave function” (or “decoherence” in its broadest meaning) in quantum mechanics is the nonlinearities already present in the theory via nonabelian gauge interactions.
