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.
2015 Nobel-laureate Takaaki Kajita opened NuPhys19 by confirming that construction of Hyper-Kamiokande will begin this year.
This is the most precise measurement so far of a parameter with implications for the stability of the vacuum.
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 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.
The 2020s will sort current anomalies in fundamental physics into discoveries or phantoms, says Ben Allanach.
A large discrepancy in nuclear decay rates has received new experimental support, generating headlines about the possible existence of a fifth force.
A new measurement by ALICE casts recent debates on this bound state of a proton, neutron and Λ in a new light.
Highlights of Beauty 2019 included lepton-universality anomalies, CP violation, pentaquarks, ultra-rare decays and reports on Belle II and the LHCb upgrade.
LHCb has introduced Λb0 decays as a new probe of the flavour anomalies.
