Neutrino Mass, Vacuum Stability, and Higgs Inflation with Vector-Like Quarks and a Right-Handed Neutrino
Analysis
This paper explores an extension of the Standard Model to address several key issues: neutrino mass, electroweak vacuum stability, and Higgs inflation. It introduces vector-like quarks (VLQs) and a right-handed neutrino (RHN) to achieve these goals. The VLQs stabilize the Higgs potential, the RHN generates neutrino masses, and the model predicts inflationary observables consistent with experimental data. The paper's significance lies in its attempt to unify these disparate aspects of particle physics within a single framework.
Key Takeaways
- •Proposes an extension to the Standard Model to address neutrino mass, vacuum stability, and Higgs inflation.
- •Introduces vector-like quarks (VLQs) and a right-handed neutrino (RHN).
- •VLQs stabilize the Higgs potential, and the RHN generates neutrino masses.
- •Predicts inflationary observables consistent with experimental data.
- •Provides a unified framework for addressing multiple problems in particle physics.
“The SM+$(n)$VLQ+RHN framework yields predictions consistent with the combined Planck, WMAP, and BICEP/Keck data, while simultaneously ensuring electroweak vacuum stability and phenomenologically viable neutrino masses within well-defined regions of parameter space.”
