This theory ultimately became known as the Standard Model, but in order to get there several vital discoveries had to be made, including that of quarks. Most puzzling was the existence of ...

A CERN experiment has revealed that up quarks outnumber down quarks after certain collisions, defying predictions. This ...

Quarks are particles that are not only hard ... (While this isn't a part of the Standard Model, the theory – framed as a paradox – goes that it would be more likely to see organized groups ...

Meanwhile, the theory went, another group of particles called mesons were composed of quarks and their antimatter partners, antiquarks. Gell-Mann’s theory implied that even more complex quark ...

A group of physicists took a mathematical ... explain the strong force—the one we use today, based on quarks and gluons—string theory faded from the scene. But again, like most revolutions ...

An intriguing observation, with far-reaching consequences, was made by the NA61/SHINE experiment group ... quarks into protons, neutrons or mesons is the strong interaction, described by a theory ...

Unlike the quantum theory of electromagnetism, Quantum Chromodynamics has the property that the fundamental particles (quarks and gluons) interact more and more weakly when probed at higher and higher ...

Specifically, the subatomic particles that make up those protons and neutrons, called quarks, slow down massively ... the European Muon Collaboration, the group that discovered it.
