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 ...

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 ...

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 ...

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

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 ...

When an energetic quark or gluon gets knocked free during a proton-proton collision, this free "parton" first generates a shower of other partons, which then "fragment" to form hadrons (h) such as ...
