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.
Heavier quarks, such as charm, can provide unique insights as they are produced early in the collisions, and their interactions with the QGP differ from their lighter cousins.
The ALICE collaboration is now using the scattering between particles produced in collisions at the LHC to constrain interaction potentials in a new way.
What a proton is depends on how you look at it, or rather on how hard you hit it.
These results demonstrate that with the correct treatment of biases from the parton–parton interactions the observed suppression in Pb–Pb collisions is consistent with results from p–Pb collisio...
The quarkonium yield is suppressed in heavy-ion collisions when compared with proton–proton collisions because the binding force is screened by the hot and dense medium.
