The ALICE experiment of the Large Hadron Collider has, for the first time, directly measured a phenomenon known as the "deadcone," which has allowed physicists to directly measure the mass of a ...

Amid the chaotic chains of events that ensue when protons smash together at the Large Hadron Collider in Europe, one particle has popped up that appears to go to pieces in a peculiar way. All eyes are ...

The Large Hadron Collider (LHC) is also a big hadron discoverer. The atom smasher near Geneva, Switzerland, is most famous for demonstrating the existence of the Higgs boson in 2012, a discovery that ...

On Tuesday, CERN’s Large Hadron Collider (LHC) switched on its data collectors, beginning a new run after several years of downtime for maintenance and upgrades. But even as particle physicists ...

While technically protons have tons of quarks (and anti-quarks), three of those quarks, known as valence quarks, make up the positive charge of a proton. Hence, the three-quark label. Throughout the ...

Physicists at the European Organization for Nuclear Research (CERN) announced on 5 July that they had observed three exotic new types of particles that had never been seen before—shining a light into ...

A few billionths of a second after the Big Bang—currently the most widely accepted theory of how the universe was formed—elementary particles, including protons and neutrons, did not exist. Instead, ...

Two experiments at CERN's Large Hadron Collider made a discovery that links the two heaviest elementary particles of the Standard Model: the Higgs boson and top quark. Scientists working in the CMS ...

You’d be surprised at how many times someone has asked whether the Large Hadron Collider (LHC) could collide mundane things, like a sandwich. The answer is, not quite… but almost! It’s sort of a long ...

Welcome to the family! Scientists using CERN’s Large Hadron Collider in Europe have discovered two new subatomic particles. The discovery of the two related particles, submitted to the journal ...
