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 CDF Collaboration at Fermilab has confirmed that a subatomic particle called the Bs meson flips between matter and ...

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 ...

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 ...

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 ...

For more than half a century, particle physicists have theorized the existence of a “glueball,” a particle made entirely of gluons. While the past few decades have produced some compelling candidates, ...

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 ...
