Probing the Majorana nature of TeV-scale radiative seesaw models at the ILC

TL;DR

This paper explores how TeV-scale radiative seesaw models, which generate tiny neutrino masses through quantum effects, can be tested at the ILC, focusing on their extended scalar sector and Majorana nature.

Contribution

It demonstrates that the Majorana nature of these models can be directly tested through electron-positron and electron-electron collision experiments at the ILC.

Findings

Majorana nature can be tested at the ILC

Extended scalar sector influences collider signatures

Electron-electron collisions are key to probing Majorana properties

Abstract

Two important features of TeV-scale radiative seesaw models, in which tiny neutrino masses are generated at the quantum level, are an extended scalar (Higgs) sector and the Majorana nature. We study phenomenological aspects of these models at the ILC. It is found that the Majorana nature of the models can be tested directly via the electron-positron and electron-electron collision experiments.
