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 the past half century or so, a theory known by the understated name of the Standard Model has dominated the field of particle physics. This theory provides us with a detailed description of the 17 ...

The magnum opus of particle physics is far from complete, requiring physicists to devise many alternatives—some weirder than ...

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, ...

No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

In this video, we explore the Standard Model of particle physics, detailing the quantum field theories that describe fundamental particles and forces in the universe. Topics covered include: - ...

Roger Jones receives funding from STFC. I am a member of the ATLAS Collaboration As a physicist working at the Large Hadron Collider (LHC) at Cern, one of the most frequent questions I am asked is ...

Dark matter makes up 27 percent of the universe’s total mass and energy — nearly five times more than “normal” matter that comprises planets and stars. True to its name, dark matter is hard to ...

Tokyo, Japan – Researchers from Tokyo Metropolitan University have used computer simulations to model how a composite material reacts to loading. They studied a particle model of a pillar of stiffer ...

Electromagnetism and the weak nuclear force are two distinct fundamental forces. That wasn’t always the case. How many fundamental forces are there in our universe? For particle physicists, answering ...

Ten years ago, scientists announced the discovery of the Higgs boson, which helps explain why elementary particles (the smallest building blocks of nature) have mass. When you purchase through links ...

The LHCb collaboration at CERN has confirmed the observation of an ultra-rare particle decay that has puzzled physicists for ...
