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 ...

Quarks are elemental particles, with no sub-structure. Understanding them is crucial to learning how physics works on the smallest levels. By studying collisions of incredibly small particles made up ...

Antimatter is a strange beast. Physicists believe that for every particle that exists in our universe, there is an antiparticle which is identical but has the opposite charge. But when antimatter ...

The Large Hadron Collider (LHC) sparked worldwide excitement in March as particle physicists reported tantalizing evidence for new physics — potentially a new force of nature. Now, our new result, yet ...

Physicists at Cern have discovered a plethora of new exotic particles being created in the collisions produced by the Large Hadron Collider over the past few years. So many have been found, in fact, ...

A proton isn't just three quarks and gluons, but a sea of dense particles and antiparticles inside. The more precisely we look at a proton and the greater the energies that we perform deep inelastic ...

Harry Cliff is a member of the LHCb Collaboration, though he was not directly involved in the work described in this article. Everything you see around you is made up of elementary particles called ...
