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.
Among the highlights at Strangeness in Quark Matter 2019 were reports on where strangeness enhancement is localised in phase space.
Bottomonia are the first hadrons that do not seem to "flow" in heavy-ion collisions at the LHC.
The meeting was inspired by several recent proposals to take advantage of the unique environment of heavy-ion collisions at the LHC to search for new phenomena.
