Bosons act as the "messengers" that allow fermions to interact with one another. Each fundamental force has its corresponding boson:

These carry a "color charge" and are subject to the strong nuclear force. There are six flavors: up, down, charm, strange, top, and bottom. Protons (two up, one down) and neutrons (one up, two down) are formed from these. elementary particles in nuclear physics pdf

Nuclear physics traditionally studies the atomic nucleus (protons and neutrons). However, modern nuclear physics is inseparable from particle physics because protons and neutrons are not elementary—they are composed of quarks. Understanding nuclear forces, decay processes, and high-energy collisions requires knowledge of elementary particles such as quarks, leptons, and gauge bosons. Bosons act as the "messengers" that allow fermions

In 1930, Wolfgang Pauli proposed a "desperate remedy." He suggested that a second, invisible particle was being emitted alongside the electron—a particle with no charge and almost no mass. This "little neutral one," or neutrino , carried away the missing energy. Protons (two up, one down) and neutrons (one

This was the first crack in the wall of "classical" nuclear physics. It introduced the , the second fundamental force at play inside the nucleus. Unlike the strong force, which binds the nucleus together, the weak force has the unique ability to change the flavor of particles. It is the mechanism by which the sun burns, transmuting hydrogen into helium.

The strongest force, acting over very short distances (femtometers) to bind the nucleus.

Elementary particles interact with each other through the exchange of other particles, known as gauge bosons. The four fundamental forces of nature are:
