Physicists have struggled for seven decades with the question of why there is more matter in the universe than antimatter.

Professor Claudia Ratti explains about quarks and gluons, including the so-called Quark-Gluon Plasma, plus Quantum ...

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 ...

Scientists have achieved an incredible feat—mapping the forces inside a proton with extreme precision, uncovering the immense ...

Protons sit in the nuclei of all atoms, but they are not fundamental particles: They are made of three quarks held together by the strong nuclear force. The strength of this interaction is actually ...

Most top quarks are produced in top–antitop pairs by the strong force. The production rate for this process is substantial (it has a cross-section of about 7 picobarns) and the presence of two ...

Scientists have now mapped the forces acting inside a proton, showing in unprecedented detail how quarks—the tiny particles within—respond when hit by high-energy photons. The international ...

CBC’s Quirks & Quarks is an award-winning radio science program, bringing listeners to the cutting edge of scientific inquiry for more than 45 years. Every week, the program presents the people ...

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!
