Photon photon scattering in a 3-3-1 model

TL;DR

This paper investigates how exotic particles predicted by the 331 model, such as doubly charged bileptons and exotic quarks, could cause observable deviations in light-by-light scattering at future colliders, offering an indirect test of the model.

Contribution

It presents a detailed analysis of the virtual effects of exotic particles in the 331 model on light-by-light scattering, highlighting potential measurable deviations from the standard model.

Findings

Doubly charged vector bileptons cause significant deviations in scattering cross sections.

Exotic quarks with charges 5/3 e and -4/3 e also influence the scattering process.

Deviations are detectable at future linear colliders with energies 0.3--1 TeV.

Abstract

We analyze the effects of a doubly charged vector bilepton as well as exotic quarks with charge 5/3 e and -4/3 e on light by light scattering. We consider mass values in the range 0.3--1 TeV, which would be reached at the planned future linear colliders. It is found that such exotic particles, especially the doubly charged vector bilepton, give raise to remarkable deviations from the standard model cross section. The virtual effects arising from these particles would provide an indirect test to a particular model which is based on the SU_c(3) X SU_L(3) X U_x(1) gauge symmetry, known as the 331 model, where such particles are a natural prediction.
