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

open access: yesJournal 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

open access: yesJournal 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)

Topflavor: A Separate SU(2) for the Third Family [PDF]

open access: yes, 1996
We consider an extended electroweak gauge group: SU(2)$_1 \times$ SU(2)$_2 \times$ U(1)$_Y$ where the first and second generation of fermions couple to SU(2)$_1$ and the third generation couples to SU(2)$_2$.

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

open access: yesPhysical 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.

Relevance of induced gauge interactions in decoherence. [PDF]

open access: yes, 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

Impact of dimension-8 SMEFT operators on diboson productions

open access: yesJournal of High Energy Physics, 2023
We for the first time identify all the dimension-8 (dim-8) SMEFT operators that can have an interference with the SM with E 4/Λ4 enhancement in the high energy limit for the processes q q ¯ → WW / WZ $$ q\overline{q}\to WW/ WZ $$ .

Hamiltonian Formulation of Jackiw--Pi 3-Dimensional Gauge Theories [PDF]

open access: yes, 1998
A 3-dimensional non-abelian gauge theory was proposed by Jackiw and Pi to create mass for the gauge fields. However, the quadratic action obtained by switching off the non-abelian interactions possesses more gauge symmetries than the original one ...

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

open access: yes, 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.

Fermion Condensate Model of Electroweak Interactions [PDF]

open access: yes, 2005
A new dynamical symmetry breaking model of electroweak interactions is proposed based on interacting fermions. Two fermions of different SU_{L}(2) representations form a symmetry breaking condensate and generate the lepton and quark masses.

Tests for a Strong Electroweak Sector at Future e^+e^- High Energy Colliders [PDF]

open access: yes, 1997
The study of the scattering at high energy of the gauge bosons W and Z, in particular longitudinally polarized W and Z, can clarify the mechanism of spontaneous symmetry breaking in the Standard Model of the electroweak interactions.
