The fact there is so much more matter than antimatter in the universe is one of the greatest puzzles in physics, but new ...

It leverages high-energy collisions of fundamental particles to study Quantum Chromo-Dynamics (QCD), the theory governing the strong force, where partons (quarks, antiquarks, and gluons) interact via ...

Thus, the direction of the top quarks created by such collisions should change, too. Wildly, that means that the number of quarks created should depend on what time of day the collisions occur!

Top quarks follow the rules of special relativity day and night. Is there a time of day or night at which nature's heaviest elementary particle stops obeying Einstein's rules? The answer to that ...

The fundamental particles are summarised by the standard model. This includes leptons (such as the electron), the quarks that make up protons and neutrons, and gauge bosons, which mediate forces ...

This mixture was dominated by quarks – fundamental bits of matter – and by gluons, carriers of the strong force that normally “glue” quarks together into familiar protons and neutrons and other ...
