Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have uncovered experimental evidence that particles of matter emerging from energetic subatomic smashups retain a key ...

For more than a decade, physicists have argued (and counter-argued) that a subatomic particle can be separated from certain quantum properties, such as its spin—a phenomenon known as the Cheshire cat ...

Spin correlations within a particle collider may help crack one of the biggest mysteries known, said physicist Zhoudunming Tu.

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

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 ...

Polarized proton containing spinning quarks and gluons (represented by right-handed and left-handed spirals). The negative Δg solutions (blue) are disfavored relative to the positive Δg solutions (red ...

What is everything made of? It’s the fundamental question that lies at the heart of particle physics. Today, scientists are using gigantic, atom-smashing particle accelerators to probe deeper into the ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...
