Page 2: Research news on Strong interaction

The strong interaction as a research area encompasses theoretical and experimental studies of the fundamental force described by quantum chromodynamics (QCD), which governs the dynamics of quarks and gluons and the structure of hadrons and nuclei. It includes investigations of color confinement, asymptotic freedom, chiral symmetry breaking, and the phase structure of strongly interacting matter, such as the quark–gluon plasma. Methodologically, it spans perturbative QCD at high energies, lattice QCD and effective field theories at low energies, and phenomenology in high-energy collider, fixed-target, and heavy-ion experiments to test and refine the Standard Model’s strong sector.

Independent measurement strengthens the case for toponium

A new independent measurement by the CMS experiment at the LHC is consistent with the existence of the most massive composite particle ever observed, the momentary union of a top quark and its antiquark

ALICE sees new sign of primordial plasma in proton collisions

The ALICE Collaboration takes a step further in addressing the question of whether a quark–gluon plasma can be formed in proton–proton and proton–nucleus collisions. In the first few microseconds after the Big Bang, the universe ...

Beam-spin asymmetry study puts proton models to the test

Getting an up-close view of life at the cellular level can be as simple as placing onion skin under a microscope and adjusting the knobs. Peering deeper, into the heart of the atoms within, isn't as easy. It requires peeling ...
