# An inverse seesaw model with global $U(1)_H$ symmetry

## TL;DR

This paper introduces an inverse seesaw model with a global $U(1)_H$ symmetry that naturally generates tiny neutrino masses and discusses its phenomenology and testability at the LHC.

## Contribution

It presents a novel inverse seesaw model utilizing a global $U(1)_H$ symmetry to induce small Majorana masses via a triplet scalar's VEV, aligning with experimental constraints.

## Key findings

- The model successfully explains tiny neutrino masses.
- It predicts exotic particles and a Goldstone boson from symmetry breaking.
- Potential signatures at the LHC are identified.

## Abstract

We propose an inverse seesaw model based on hidden global symmetry $U(1)_H$ in which we realize tiny neutrino masses with rather natural manner taking into account relevant experimental bounds. The small Majorana mass for inverse seesaw mechanism is induced via small vacuum expectation value of a triplet scalar field whose Yukawa interactions with standard model fermions are controlled by $U(1)_H$. We discuss the phenomenology of the exotic particles present in the model including the Goldstone boson coming from breaking of the global symmetry, and explore testability at the Large Hadron Collider experiments.
