Summary
We discovered a novel relationship between neutrino and charged fermion masses. This connection is predicted by a specific type of particle physics model, the left-right symmetric model.
Area of Science:
- Particle Physics
- Neutrino Physics
- Fermion Mass Relations
Background:
- Understanding the origins of fermion mass is a fundamental challenge in particle physics.
- Neutrino masses are particularly intriguing due to their small values and unique properties.
Purpose of the Study:
- To investigate a potential relationship between the mass differences of neutrinos and charged fermions.
- To explore if a specific theoretical framework can predict this observed mass relation.
Main Methods:
- Analysis of experimental neutrino mass data.
- Theoretical calculations within the framework of a left-right symmetric model.
- Comparison of predicted mass relations with observed fermion mass patterns.
Main Results:
- An intriguing relation was found between neutrino mass squared differences and charged fermion masses: |m(ν₃)² -m(ν₁)²|:(m(ν₂)²-m(ν₁)²)::V(tb)⁴m(τ)²m(b)²/m(t)²:V(cs)⁴m(μ)²m(s)²/m(c)².
- This specific mass relation is shown to be predictable within a left-right symmetric model.
Conclusions:
- The study reveals a significant connection between neutrino and charged fermion mass spectra.
- Left-right symmetric models offer a potential explanation for the observed neutrino and charged fermion mass hierarchies.

Subatomic Particles
Dalton was only partially correct about the particles that make up matter. All matter is composed of atoms, and atoms are composed of three smaller subatomic particles: protons, neutrons, and electrons. These three particles account for the mass and the charge of an atom.
Electron Behavior
Electrons are negatively charged subatomic particles attracted to and orbit around the positively-charged nucleus of an atom. They reside in spaces associated with energy levels called shells and are further organized into subshells and orbitals within each shell.
Electrons Orbit the Nucleus
Electrons are found in specific locations outside of the nucleus. The shell in which an electron resides indicates the general energy level of the electron: those closer to the nucleus have less energy,...

Atomic Radii and Effective Nuclear Charge
The elements in groups of the periodic table exhibit similar chemical behavior. This similarity occurs because the members of a group have the same number and distribution of electrons in their valence shells.
Nuclear Stability
Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.

Atomic Structure
All matter is composed of atoms, the smallest individual units of elements. Each atom is made up of three subatomic particles: protons, neutrons, and electrons. Together, these three particles account for the mass and the charge of an atom.The History of Atomic TheoryThe first person to propose that everything on Earth is made up of tiny particles was the Greek philosopher Democritus, around 450 B.C. He used the term atomos, Greek for “indivisible,” from which the modern term “atom” is derived.
