Physicists just discovered a brand-new particle that appears to be an exotic cousin to the protons and neutrons that make up ...

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 ...

Scientists working on CERN’s ALICE experiment have reported the first observation of a distinctive flow pattern among quarks ...

Physicists working on the LHCb experiment at CERN’s Large Hadron Collider have discovered a new subatomic particle called the ...

The new particle, named Xi-cc-plus, carries two heavy charm quarks and is about four times heavier than an ordinary proton.

His research enabled the discovery that protons and neutrons are made of smaller particles, contributing to a fuller picture of the subatomic universe. By Katrina Miller Katrina Miller earned a Ph.D.

Theorists have calculated how quickly a melted soup of quarks and gluons -- the building blocks of protons and neutrons -- transfers its momentum to heavy quarks. The calculation will help explain ...

Protons might be stretchier than they should be. The subatomic particles are built of smaller particles called quarks, which are bound together by a powerful interaction known as the strong force. New ...

Probing ever deeper into the inner world of the atom, nuclear physicists have uncovered an increasingly baffling collection of tiny particles. Besides the familiar neutrons, electrons and protons, ...

Protons make up most of the visible universe. Now, in a new study published in the August 18 issue of the journal Nature, scientists find that because of the strange nature of quantum physics, protons ...
