Studying top quarks at high and not-so-high energies

CERN's Large Hadron Collider (LHC) is famous for colliding protons at world-record energies—but sometimes it pays to dial down the energy and see what happens under less extreme conditions. The LHC started operation in ...

Evidence of top quarks in collisions between heavy nuclei

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 collaboration has seen evidence ...

Boosting computing power for the future of particle physics

A new machine learning technology tested by an international team of scientists including MIT Assistant Professor Philip Harris and postdoc Dylan Rankin, both of the Laboratory for Nuclear Science, can spot specific particle ...

Zooming in on top-quark production

As the heaviest known elementary particle, the top quark has a special place in the physics studied at the Large Hadron Collider (LHC) at CERN. Top quark-antiquark pairs are copiously produced in collisions recorded by the ...
