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 ...

For decades, physicists have relied on the principle of symmetry to simplify and understand the complex behaviors of subatomic particles. Symmetry in physics basically means that some rules of nature ...

In their search for more flavors of Higgs bosons, a team of researchers at CERN stumbled across what could be evidence of the smallest matter-antimatter particle ever. The hypoethical particle, known ...

Inside the Large Hadron Collider, protons slam together at nearly the speed of light, creating a brief fireball of quarks and ...

Schematic picture of the predicted Tetraquark, T bc, made of four quarks: beauty, charm quarks and two light anti-quarks. Exploring the complex domain of subatomic particles, researchers at the The ...

Physicists have shown that particles produced in collimated sprays called jets retain information about their origins in subatomic particle smashups. Physicists at the U.S. Department of Energy's (DOE ...

current theory that attempts to describe matter. Their research will be published in Physical Review Letters (in press). "It could mean some of the standard and accepted theories on matter will need ...

As they probe deeper into the heart of the atom, discovering ever smaller and more mysterious particles and particles within particles, scientists have succeeded in bringing the once stable world of ...
