Measuring properties of a dark photon from semi-invisible decay of the Higgs boson

Journal of High Energy Physics, 2022
Considerable efforts have been dedicated to discovering a dark photon via the decay of the Higgs boson to a photon and an invisible particle. A subject that is still mostly unexplored is which properties of the dark photon could be measured at the LHC if

The dark side of the proton

Journal of High Energy Physics, 2022
We study the sensitivity of the High-Luminosity LHC to a light baryonic dark photon B, primarily coupled to quarks, as a constituent of the proton. This is achieved by allowing for a dark photon parton distribution function (PDF) in the PDF evolution ...

Trinification from E 6 symmetry breaking

Journal of High Energy Physics, 2023
In the context of E6 Grand Unified Theories (GUTs), an intriguing possibility for symmetry breaking to the Standard Model (SM) group involves an intermediate stage characterized by either SU(3) × SU(3) × SU(3) (trinification) or SU(6) × SU(2).

Anomalous gauge interactions in photon collisions at the LHC and the FCC [PDF]

, 2017
The forward proton detectors recently installed and operating at the LHC open the possibility to observe photon collisions with high precision, providing a novel window on physics beyond the Standard Model.

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.

Interacting quintessence from new formalism of gravitoelectromagnetism formulated on a geometrical scalar–tensor gauge theory of gravity [PDF]

Physics of the Dark Universe, 2018
We derive an interacting quintessence model on the framework of a recently introduced new class of geometrical scalar-tensor theories of gravity formulated on a Weyl-Integrable geometry, where the gravitational sector is described by both a scalar and a tensor metric field.

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)

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

, 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.

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

, 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 ...

Fermion Condensate Model of Electroweak Interactions [PDF]

, 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.
