Explaining Solar Neutrinos with Heavy Higgs Masses in Partial Split Supersymmetry

TL;DR

This paper investigates how Partial Split Supersymmetry with R-parity violation can naturally explain solar neutrino masses, aligning with experimental data, especially in the heavy Higgs decoupling limit.

Contribution

It demonstrates that the model can produce realistic neutrino masses at one-loop level, with a natural explanation for the solar neutrino mass difference.

Findings

Model predictions agree with experimental neutrino data.

Small solar neutrino mass difference explained in heavy Higgs decoupling limit.

One-loop calculations validate the model's viability.

Abstract

Partial Split Supersymmetry with violation of R-parity as a model for neutrino masses is explored. It is shown that at the one-loop level the model can give predictions that are in agreement with all present experimental values for the neutrino sector. An analytical result is that the small solar neutrino mass difference can be naturally explained in the decoupling limit for the heavy Higgs mass eigenstates.
