Nuclear physics research is focused on understanding the matter composed of quarks and gluons, which makes up 99% of the mass of the universe. Most of this matter is found at the core of atoms, the ...

The Standard Model is a kind of periodic table of the elements for particle physics. But instead of listing the chemical elements, it lists the fundamental particles that make up the atoms that make ...

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 ...
