And if they are massive enough to decay into a top quark–antiquark pair, this should dominate the way they decay inside detectors, with the two massive quarks splintering into "jets" of particles.

Ordinary baryons are hadrons that include the proton and neutron of an atom, each made up of three-quark combinations, while hadronic particles known as mesons are formed from quark-antiquark pairs.

A candidate event for a top quark–antiquark pair recorded by the CMS detector. Such an event is expected to produce an electron (green), a muon (red) of opposite charge, two high-energy “jets ...

“The thing you call the ‘quark’ might have quark-antiquark pairs and glue and all the rest built into it,” explained Thomas Cohen, a physics professor at the University of Maryland. Quantum ...

Some quarks produced from smashed protons are massive enough to decay into top quark-antiquark pairs, or tt-bar. If this happens, protons will disintegrate into streams of particles .

Quark-antiquark pairs are also thought to be a major component of the vacuum that pervades our Universe. Instead of being empty, the vacuum is thought to be teeming with a complex mix of these ...

However, these quark–antiquark pairs are far less sensitive to the electroweak interaction and do not tell us about origins of symmetry breaking nearly as effectively as single top quarks. To work ...

“Because in the intrinsic charm quark scenario, the quark-antiquark pair is attached to more than one of the up and down quarks in the proton they travel with. That’s why the charm quarks ...

Conventional and exotic states with a pair of charmed quark-antiquark observed in Beijing Peer-Reviewed Publication. Science China Press ...

However, if gluons are real, then the electron-positron annihilation should also produce a gluon alongside the quark-antiquark pair, and this gluon should also hadronize into a third jet.
