# On the Seesaw Scale in Supersymmetric SO(10) Models

## TL;DR

This paper proposes a new supersymmetric SO(10) model that generates the seesaw scale for neutrino masses, emphasizing the role of Goldstone modes in $U(1)_{B-L}$ symmetry breaking.

## Contribution

Introduction of a novel model with spinor superfields to naturally generate the seesaw scale in supersymmetric SO(10) frameworks.

## Key findings

- Seesaw scale generated below unification scale
- Goldstone mode plays a key role in symmetry breaking
- Model consistent with neutrino mass observations

## Abstract

The seesaw mechanism, which is responsible for the description of neutrino masses and mixing, requires a scale lower than the unification scale. We propose a new model with spinor superfields playing important roles to generate this seesaw scale, with special attention paid on the Goldstone mode of the $U(1)_{B-L}$ symmetry breaking.
