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.
The LHC’s physics programme has transformed our understanding of elementary particles, writes Michelangelo Mangano.
The quark-gluon plasma has a characteristic angular scale below which high-momentum shower components are not resolved, but interact as a single partonic fragment.
The LHCb experiment has observed new beauty-baryon states, consistent with theoretical expectations for excited Ωb− baryons.
A new measurement by ALICE casts recent debates on this bound state of a proton, neutron and Λ in a new light.
When fewer than half the available lead nucleons merge and form a quark–gluon plasma, the spectators generate the strongest electromagnetic fields yet probed by scientists.
The 2019 edition of New Trends in High Energy Physics had an emphasis on heavy-ion physics and strong interactions.
HADRON2019 reviewed studies of exotic states at facilities around the world.
