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 ...

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 ...

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 ...

Scientists have discovered a common thread between the monstrous black holes that lurk at the hearts of galaxies and subatomic glass condensates created in collisions of atomic nuclei. When you ...

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

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 ...
