A Consistent Theory of Kinetic Mixing and the Higgs Low-Energy Theorem [PDF]

open access: yesPhys. Rev. Lett. 129, 171801 (2022), 2022
Extensions of the Standard Model of particle physics with new Abelian gauge groups allow for kinetic mixing between the new gauge bosons and the hypercharge gauge boson, resulting in mixing with the photon. In many models the mixing with the hypercharge gauge boson captures only part of the kinetic mixing term with the photon, since the new gauge ...

ANOMALOUS GAUGE BOSON INTERACTIONS [PDF]

open access: yes, 1997
We discuss the direct measurement of the trilinear vector boson couplings in present and future collider experiments. The major goals of such experiments will be the confirmation of the Standard Model (SM) predictions and the search for signals of new physics.

On the possibility of a search for the $L_\mu - L_\tau$ gauge boson at Belle-II and neutrino beam experiments [PDF]

open access: yes, 2016
We study the possibilities on the search of the light and weakly interacting gauge boson in the gauged $L_\mu - L_\tau$ model. Introducing the kinetic mixing at the tree-level, the allowed parameter regions for the gauge coupling and kinetic mixing ...

Lμ-Lτ gauge-boson production from lepton flavor violating τ decays at Belle II [PDF]

open access: yes, 2017
$L_\mu -L_\tau$ gauge boson ($Z'$) with a mass in the MeV to GeV region can resolve not only the muon $g-2$ excess, but also the gap in the high-energy cosmic neutrino spectrum at IceCube.

Emergent Gauge Bosons [PDF]

open access: yes, 2001
The old idea that the photon is a Goldstone boson emergent from a spontaneously broken theory of interacting fermions is revisited. It is conjectured that the gauge-potential condensate has a vacuum expectation value which is very large, perhaps the GUT/Planck momentum scale, but that the magnitude of the effective potential which generates it is very ...

Double-real corrections at $${{\mathcal {O}}(\alpha \alpha _s)}\,$$O(ααs)to single gauge boson production [PDF]

open access: yes, 2016
We consider the $${{\mathcal {O}}(\alpha \alpha _s)}\,$$O(ααs)corrections to single on-shell gauge boson production at hadron colliders. We concentrate on the contribution of all the subprocesses where the gauge boson is accompanied by the emission of ...

Partition Function of Chiral Boson on 2-Torus from Floreanini-Jackiw Lagrangian [PDF]

open access: yes, 2013
We revisit the problem of quantizing a chiral boson on a torus. The conventional approach is to extract the partition function of a chiral boson from the path integral of a non-chiral boson. Instead we compute it directly from the chiral boson Lagrangian

Gauge fields as constrained composite bosons

open access: yesPhysics Letters B, 2021
We reconsider a scenario in which photons and other gauge fields appear as the composite vector bosons made of the fermion pairs that may happen with or without spontaneous violation of Lorentz invariance. The class of composite models for emergent gauge fields is proposed, where these fields are required to be restricted by by the nonlinear covariant ...

LHC constraints on gauge boson couplings to dark matter [PDF]

open access: yes, 2015
Collider searches for energetic particles recoiling against missing transverse energy allow to place strong bounds on the interactions between dark matter (DM) and standard model particles.

Measurement of VH, H → b b ¯ $$ \mathrm{H}\to \mathrm{b}\overline{\mathrm{b}} $$ production as a function of the vector-boson transverse momentum in 13 TeV pp collisions with the ATLAS detector

open access: yesJournal of High Energy Physics, 2019
Cross-sections of associated production of a Higgs boson decaying into bottomquark pairs and an electroweak gauge boson, W or Z, decaying into leptons are measured as a function of the gauge boson transverse momentum.
