New results from the ALICE collaboration highlight the quark-mass and colour-charge dependence of energy loss in the ...

In a new development at CERN, researchers at the LHCb collaboration have determined the spin-parity of singly heavy charm ...

On March 2, 1995, the top quark discovery at Fermilab was announced by scientists on the CDF and DZero collaborations, and ...

The first, long-sought evidence for the production of single top quarks, by the weak interaction, has been reported from a sophisticated analysis of a large number of proton–antiproton ...

A proton’s valence quarks (blue, red, and green), quark-antiquark pairs, and gluons (springs). Scalar gluon activity (pink) extends beyond the electric charge radius (orange) that surrounds the ...

Graphic showing the transverse motion of a quark (green sphere) inside a proton whose spin is aligned to its direction of ...
