# On the phenomenology of a non-linear $U(1)_{\rm Y}$ sector

@inproceedings{Fabritiis2021OnTP, title={On the phenomenology of a non-linear \$U(1)\_\{\rm Y\}\$ sector}, author={Paolo Fabritiis and P. C. Malta and Jos'e Abdalla Helayel-Neto}, year={2021} }

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… Expand
