On the phenomenology of a non-linear U(1)Y sector

  title={On the phenomenology of a non-linear U(1)Y sector},
  author={Paolo Fabritiis and P. C. Malta and Jos{\'e} Abdalla Helay{\"e}l-Neto},
In this work we perform a non-linear extension of the U(1)Y sector of the Standard Model leading to novel quartic effective interactions between the neutral gauge bosons. We study the induced non-linear effects through high-energy processes resulting in three photons, namely, Z-boson decay and electron-positron annihilation. We also discuss the scattering of neutral gauge bosons induced at tree level. Available experimental data on these processes do not yield viable lower bounds on the mass…

Non-abelian effects in non-linear quantum electrodynamics and in Z0 decay into three photons
Abstract The three-photon decay mode of the neutral weak boson Z0 is studied as an example of a more general class of reactions such as the light by light and the Delbruck scatterings, the splitting
Quartic Gauge Boson Couplings ∗
We review the recent progress in studying the anomalous electroweak quartic gauge boson couplings (QGBCs) at the LHC and the next generation high energy ee linear colliders (LCs). The main focus is
▪ Abstract We review studies of the trilinear gauge-boson couplings at the Tevatron proton-antiproton collider from data collected by the CDF and DO collaborations during the period 1992–1996. The
The price of an electroweak monopole
Abstract In a recent paper, Cho, Kim and Yoon (CKY) have proposed a version of the SU ( 2 ) × U ( 1 ) Standard Model with finite-energy monopole and dyon solutions. The CKY model postulates that the

The lowest-dimensional effective Lagrangians describing the decay of a neutral massive vector boson into three photons are considered and a generalization of some earlier results appearing in the literature is generalized.
Electroweak monopoles with a non-linearly realized weak hypercharge
We present a finite-energy electroweak-monopole solution obtained by considering non-linear extensions of the hypercharge sector of the Electroweak Theory, based on logarithmic and exponential
Z boson decay into photons
We perform a completeO(α4) calculation of the coupling of theZ boson to three photons via both fermion andW boson loops and keeping the full dependence on the quark andW masses. To evaluate theW
Scattering of W and Z bosons at high-energy lepton colliders
We present a new study of quasi-elastic W and Z scattering processes in high-energy $$e^+e^-$$e+e- collisions, based on and extrapolating the low-energy effective theory which extends the standard
Non-linear electrodynamics from quantized strings
We compute the effective action for an abelian vector field coupled to the virtual open Bose string. The problem is exactly solved (in the “tree” and “one-loop” approximation for the string theory)
Radiative corrections to W+W− → W+W− in the electroweak standard model
Abstract The cross-section for W+W− → W+W− with arbitrarily polarized W bosons is calculated within the Electroweak Standard Model including the complete virtual and soft-photonic O (α) corrections.
