Minimal SO(10) splits supersymmetry

TL;DR

This paper presents a minimal supersymmetric SO(10) model that fits fermion masses and mixings, predicts a split supersymmetry spectrum with heavy sfermions, and forecasts rapid proton decay and specific leptonic mixing angles.

Contribution

It introduces a minimal renormalizable SO(10) model with a unique split supersymmetry breaking scenario aligning with fermion data.

Findings

Successful fit of fermion masses and mixings

Predicted proton decay rates via d=6 operators

Leptonic mixing angle theta_13 approximately 0.1

Abstract

A good fit of the fermion masses and mixings has been found in the minimal renormalizable supersymmetric SO(10). This solution needs a strongly split supersymmetry breaking scenario with gauginos and higgsinos around 100 TeV, sfermions close to 10^14 GeV and a low GUT scale of around 6 10^15 GeV. We predict fast proton decays through SO(10) type of d=6 operators and the leptonic mixing angle theta_13 approximately 0.1.
