According to our current understanding of the universe, quarks are fundamental, point-like particles: basic building blocks that are not made up of smaller particles. A recent paper from the CMS ...

Physicists just discovered a brand-new particle that appears to be an exotic cousin to the protons and neutrons that make up atoms. Those mundane subatomic particles are made up of even smaller ...

Evidence of a particle made up of four tightly bound quarks tests physicists’ understanding of the force that holds protons and neutrons together. The particles in a hadron are bound tightly together ...

Add Yahoo as a preferred source to see more of our stories on Google. For decades, physicists have relied on the principle of symmetry to simplify and understand the complex behaviors of subatomic ...

There’s a pencil lying on my desk right now. It’s not much to look at, but what if I could zoom way in and see the protons and other itty-bitty stuff inside it? My friend Ryan Corbin told me it would ...

Is there a time of day or night at which nature's heaviest elementary particle stops obeying Einstein's rules? The answer to that question, as bizarre as it seems, could tell scientists something very ...

The futurist Arthur C. Clarke famously said that “any sufficiently advanced technology is indistinguishable from magic.” Well, a team of physicists just showed that a common particle production method ...

The atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to reproduce ...

Scientists have for the first time observed quantum entanglement — a state in which particles intermingle, losing their individuality so they can no longer be described separately — between quarks.

Physicists at the world's largest atom smasher have observed two quarks in a state of quantum entanglement for the first time. The ATLAS experiment (A Toroidal LHC Apparatus) is the largest detector ...

Quantum entanglement has made its way to the top. Scientists have measured the strange quantum phenomenon of entanglement in top quarks, the heaviest fundamental subatomic particles known. It’s the ...
