Fragmentation functions are fundamental components in quantum chromodynamics (QCD), encapsulating the probability that a high-energy quark or gluon produces a specific hadron during the hadronisation ...

Illustration of the evolving shower of a charm quark (gray) radiating gluons (purple) at successively smaller angles as energy is lost, with gluon radiation suppressed within each angular “dead-cone” ...

The strong interaction is one of the fundamental forces of nature, which binds quarks into hadrons such as the proton and the neutron, the building blocks of atoms. According to the quark model, ...

CMS researchers observe quantum entanglement in top quark–antiquark pairs, revealing new insights into quantum behaviour at the smallest scales Quantum entanglement is a fascinating phenomenon in ...
