Imagine trying to prove that 1+1=2, but when you do the calculations, it turns out that the result is off by 0.1%. That scenario is similar to the riddle that’s facing physicists worldwide as they try ...

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 ...

STARKVILLE, Miss.—A Mississippi State physicist and her colleagues are the first scientists to observe how subatomic particles—known as lambda particles—are formed, helping researchers learn more ...

A team including physicists has for the first time detected subatomic particles called neutrinos created by a particle collider, namely at CERN's Large Hadron Collider (LHC). The discovery promises to ...

A global effort to gain a more complete understanding of the fundamental building blocks of the universe resumed Tuesday near Geneva, as the world’s largest particle collider restarted scientific ...

What is everything made of? It’s the fundamental question that lies at the heart of particle physics. Today, scientists are using gigantic, atom-smashing particle accelerators to probe deeper into the ...

Peter Higgs, who gave his name to the subatomic particle known as the Higgs boson, passed away at the age of 94. He was always a modest man, especially when considering that he was one of the greats ...

Scientists imagine virtual particles popping in and out of existence to explain how forces transfer between particles. koto_feja/iStock via Getty Images A clever mathematical tool known as virtual ...

Of all the subatomic particles that have any mass at all, the neutrino is the lightest by far. In comparison, the electron, itself a quantum featherweight, has a mass that is at least 500,000 times ...

A surprising and rare particle decay has left scientists puzzled as kaons, particles made up of quarks, are decaying in ways that defy current physics models. Could this anomaly indicate the existence ...

China is nearing completion of an advanced facility to measure neutrinos, the smallest subatomic particles known to physicists. Its underground central sphere will soon be sealed off and filled with ...

A complete survey of all the particle and antiparticle activity that goes on during the Sun’s 11-year cycle has found previously unknown ways these particles behave. Cosmic rays coming from outside ...
