Reconstructing SUSY and R-Neutrino Masses in SO(10)

TL;DR

This paper presents a method to reconstruct SO(10) grand unified theories by extrapolating scalar mass parameters from collider data, enabling estimation of right-handed neutrino masses within the seesaw framework.

Contribution

It introduces a novel extrapolation technique to determine high-scale parameters and right-handed neutrino masses from low-energy collider measurements.

Findings

Successful reconstruction of SO(10) parameters near the unification scale.

Estimation of the heaviest right-handed neutrino mass.

Demonstration of method feasibility with projected collider precision.

Abstract

We report on the extrapolation of scalar mass parameters in the lepton sector to reconstruct SO(10) scenarios close to the unification scale. The method is demonstrated for an example in which SO(10) is broken directly to the Standard Model, based on the expected precision from coherent LHC and ILC collider analyses. In addition to the fundamental scalar mass parameters at the unification scale, the mass of the heaviest right-handed neutrino can be estimated in the seesaw scenario.
