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 ...

These results show that the response of particle yields to a quark phase grows with the number of strange quarks the particles contain. "Multi-strange particles could be a promising probe of the ...

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 ...
