As if atoms weren’t already mind-blowingly small, never mind subatomic particles, CERN researchers in the CMS Collaboration ...

Heaviest known elementary particles and their antimatter counterparts are detected after nuclear smash-ups at the Large Hadron Collider.

High-energy collisions between protons at the LHC routinely produce top quark–antiquark pairs (tt-bar). Measuring the ...

A pair of top quarks has been detected in the detritus spraying forth from the collision of two atoms of lead.

Researchers at the CMS collaboration at CERN have reported the discovery of the smallest hadron in existence, the toponium.

High-energy collisions between protons at the LHC routinely produce top quark–antiquark pairs (tt-bar). Measuring the probability, or cross section, of tt-bar production is both an important ...

In this case, a dependence on the orientation of the experiment would mean that the rate at which top-quark pairs are produced in proton–proton collisions at the LHC would vary with time.

Representation of nuclear matter on the left and of quark matter on the right. The question mark alludes to the question of whether these liquids can be distinguished in a theoretically rigorous ...
