An unforeseen feature in proton-proton collisions previously observed by the CMS experiment at CERN's Large Hadron Collider ...

Although top quarks are routinely produced in high-energy proton collisions at the LHC, they’re notoriously unstable and decay in less than a trillionth of a trillionth of a second, earning a ...

Although the quark–gluon plasma at the LHC vanishes after about 10-23 s, scientists can study it by analysing how other particles produced in collisions move through it. The top quark is the heaviest ...

The proton, a particle found at the heart of every atom, appears to have a more complicated structure than is traditionally given in textbooks. The find could have ramifications for sensitive ...

In a first-of-its-kind experiment conducted at the world's most powerful particle accelerator, the Large Hadron Collider (LHC), scientists have attempted to discover if the universe's heaviest ...

A new type of particle may have shown up independently at two particle accelerators, physicists say. The particle, made of four quarks (the ingredients of protons and neutrons), appears to ...

It hasn’t existed since the beginning of time itself, but now scientists have managed to create what they call quark soup. This substance is believed to be the smallest, hottest, and densest ...

In the 30 years since, investigating the top quark has opened up new worlds of particle physics, and the discovery of the Higgs boson in 2012 revealed the two particles’ close association. Now ...

Protons can contain a charm quark, an elementary particle 1.5 times heavier than the proton itself. Skip to main content. Open menu Close menu. Space. Search. Search Space. Sign in.

Do top quarks, nature's heaviest elementary particle, obey Einstein's rules at all times of day and night? Scientists at the Large Hadron Collider have the answer.
