Gauge see-saw: A mechanism for a light gauge boson

open access: yesPhysics Letters B, 2017
There has been rapidly growing interest in the past decade in a new gauge boson which is considerably lighter than the standard model Z boson. A well-known example of this kind is the so-called dark photon, and it is actively searched for in various ...

Searching for flavored gauge bosons [PDF]

open access: yesJournal of High Energy Physics, 2019
Abstract Standard Model may allow an extended gauge sector with anomaly-free flavored gauge symmetries, such as L i −L j , B i −L j , and B −3L i

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

TRILINEAR NEUTRAL GAUGE BOSON COUPLINGS [PDF]

open access: yesInternational Journal of Modern Physics A, 2001
We study the CP even trilinear neutral gauge boson vertices at one-loop in the context of the Standard Model and the Minimal Supersymmetric Standard Model, assuming two of the vector bosons are on-shell. We also study the changes in the form-factors when these two bosons are off-shell.

Triple gauge boson decay of new neutral gauge bosons

open access: yesPhysics Letters B, 1989
Abstract The decay of new heavy neutral gauge bosons (Z′) into three gauge boson final states (e.g., W + W − Z) is examined within the context of E 6 superstring-inspired models. We find that the ratio of decay rates Γ(Z′→W + W − Z)/Γ(Z′→W + W − ) grows quadratically with the Z′ mass and can be as large ≅0.43 for a Z′ mass of 3 TeV.

NEW GAUGE BOSONS FROM STRING MODELS [PDF]

open access: yesModern Physics Letters A, 1996
We address the mass ranges of new neutral gauge bosons and constraints on the accompanying exotic particles as predicted by a class of superstring models. Under certain assumptions about the supersymmetry breaking parameters we show that breaking of an additional U(1)′ symmetry is radiative when the appropriate Yukawa couplings of exotic particles are

17 MeV Atomki anomaly from short-distance structure of spacetime

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
An anomaly observed recently in the $$^8 \hbox {Be}$$ 8Be nuclear transition by the Atomki collaboration hints at a weakly-coupled, light new gauge boson with a mass of about 17 MeV.

Gauge interactions and bosonized fermion liquids [PDF]

open access: yesPhysical Review Letters, 1994
We investigate fermion liquids interacting with longitudinal and transverse abelian gauge fields via bosonization. In two spatial dimensions we obtain the fermion propagator for the specific case of a Coulomb plus Chern-Simons gauge action. We discuss the relevance of this result to the Halperin-Lee-Read theory of the $ =1/2$ Landau level and ...

Measurements of WH and ZH production in the $$H \rightarrow b\bar{b}$$ H → b b ¯ decay channel in pp collisions at $$13\,\text {Te}\text {V}$$ 13 Te with the ATLAS detector

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
Measurements of the Standard Model Higgs boson decaying into a $$b\bar{b}$$ b b ¯ pair and produced in association with a W or Z boson decaying into leptons, using proton–proton collision data collected between 2015 and 2018 by the ATLAS detector, are ...
