The strong force holds together quarks, the fundamental particles that make up the protons and neutrons of the atomic nucleus, and further holds together protons and neutrons to form atomic nuclei.

Researchers have been working for decades to understand the architecture of the subatomic world. One of the knottier questions has been where the proton gets its intrinsic angular momentum, otherwise ...

Carnegie Mellon University's Professor Curtis Meyer and his research colleagues explore an uncharted world inside protons and ...

The strong force binds the fundamental particles known as quarks together to form particles such as the protons and neutrons of the atomic nucleus. Protons and neutrons are both composites of ...

One of the main differences between quarks and leptons is that leptons do not interact via the nuclear strong force and ultimately do not combine to form larger particles like quarks do.

Under normal circumstances, quarks are held together inside protons and neutrons by the strong force, which is mediated by the exchange of gluons. This property is known as 'confinement', and the ...

Physicists in this field explore the nature of the strong force by studying the theory of Quantum Chromodynamics. Unlike the quantum theory of electromagnetism, Quantum Chromodynamics has the property ...

The underlying theoretical construct in particle physics is called the Standard Model and it contains 6 quarks, 6 leptons, 4 gauge bosons, and one scalar boson (the Higgs boson), which interact ...

For example, baryons, such as protons and neutrons, are combinations of three quarks bound tightly together by strong force-carrying gluons. When individual quarks are ripped from hadrons ...

In the higher energy picture, composite protons and neutrons (composed of quarks and gluons) interact through quantum chromodynamics (QCD). This residual interaction is the strong nuclear force.
