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 ...

In a discovery that has physicists relearning how to count, three teams around the globe report that they have identified a subatomic particle consisting of five quarks -- a number never before seen ...

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 ...

Columnist Natalie Wolchover checks in with particle physicists more than a decade after the field entered a profound crisis.

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 ...

July 21, 2003--At the Conference on the Intersections of Particle and Nuclear Physics held May 2003 in New York City, researcher Stepan Stepanyan from the DOE Office of Science's Thomas Jefferson ...

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 ...
