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 ...

Researchers have announced results from a new search at the European X-ray Free Electron Laser (European XFEL) Facility at ...

Carnegie Mellon University's Professor Curtis Meyer and his research colleagues explore an uncharted world inside protons and ...

CU Boulder Professor Jamie Nagle will discuss the quarks and gluons that formed at the Big Bang in his Distinguished Research Lecture Feb. 6 Ten trillion degrees Fahrenheit is unfathomably hot—more ...

In a major milestone for particle physics, scientists at CERN’s Large Hadron Collider (LHC) have successfully observed top ...

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 ...
