The tetraquark candidate could be a bound state of a charm-up diquark and its anti-diquark.
Studies using traps and lasers not only help researchers understand nuclear structure, but also offer new ways to look for physics beyond the Standard Model.
A hidden-double-charm tetraquark observed recently by LHCb has reinvigorated the debate over whether tetraquarks are pairs of mesons or pairs of diquarks.
The ALICE collaboration recently used p–p and p–Λ pairs to perform the first study of the particle-emitting source for baryons produced in pp collisions.
Pier Francesco Monni and Philip Ilten were recognised for their exceptional contributions to the theoretical and experimental aspects of deep inelastic scattering.
Originally scheduled to be held in Paris, the fully online conference brought together a particularly large and diverse group of participants.
CMS has probed the running of the mass of the top quark for the first time - an important test of the validity of QCD, and an indirect search for unknown physics.
Jet modification effects are predicted to be strongest in this kinematic region.
Though several mysteries remain, the ALICE collaboration has uncovered evidence that quark-gluon plasmas with extreme angular momenta become polarised.
Quark Matter 2019 heard about new probes of the quark-gluon plasma, including first observations of the exotic hadron X(3872) and top-antitop production.
