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

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

Once the fifth quark was discovered it was widely expected that there would be a sixth quark ... The detector is about the size of a three-story house and looks like something out of a science fiction ...

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

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 ...

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.
