Deep in the heart of the matter, some numbers don't add up. For example, while protons and neutrons are made of quarks, nature's fundamental building blocks bound together by gluons, their masses are ...

Time evolution of the quark-antiquark pair produced by high-energy particle collisions. The pair separates in space, producing additional quark-antiquark pairs, but it still maintains the quantum ...

The result of recent research by the CMS collaboration opens the path to study in a new and unique way an extreme state of matter that is thought to have existed shortly after the Big Bang. The ...
