Though several mysteries remain, the ALICE collaboration has uncovered evidence that quark-gluon plasmas with extreme angular momenta become polarised.
The sixth conference in the series marked Spanish theorist Emilio Elizalde’s 70th birthday.
2015 Nobel-laureate Takaaki Kajita opened NuPhys19 by confirming that construction of Hyper-Kamiokande will begin this year.
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.
Updated measurements by LHCb of the angular distributions of a rare neutral B meson decay add fresh intrigue to the flavour puzzle.
Researchers trace second repeating fast radio burst to ordinary galaxy, suggesting that extreme environments are not required.
Wide-ranging discussions at TeVPA featured the DAMA signal, GeV gamma rays from the galactic centre, the 21 cm radio line, AMS's positron excess and a host of cosmic messengers.
The Standard-Model Extension provides a framework for testing CPT and Lorentz symmetries by including all operators that break them in an effective field theory.
A new fit to Planck’s 2018 data release exchanges an anomalously large lensing amplitude for a higher energy density, thereby inferring a closed universe.
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 world average using inclusive b-hadron decays to a c hadron and a charged lepton differs from exclusive semileptonic B decays by three standard deviations.
This is the most precise measurement so far of a parameter with implications for the stability of the vacuum.
The 2020s will sort current anomalies in fundamental physics into discoveries or phantoms, says Ben Allanach.
