Bound state, found state – ATLAS ties the knot on top quark pair production at threshold
Bound state, found state – ATLAS ties the knot on top quark pair production at threshold Physics at the LHC often advances by pushing into regimes once thought unreachable. One such frontier is the precise study of top-anti-top quark pairs (tt̄) near the production threshold, where subtle quantum effects may leave their imprint. A few

ALICE explores the quark–gluon plasma with light-ion collisions
ALICE explores the quark–gluon plasma with light-ion collisions In July 2025, the ALICE experiment took part in the LHC’s first-ever light-ion campaign, colliding oxygen–oxygen (O–O) and neon–neon (Ne–Ne) nuclei at a centre-of-mass energy of 5.36 TeV per nucleon pair. The short but intense runs offered a rare opportunity to explore the transition between ordinary hadronic
