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.
A symposium to celebrate the fiftieth anniversary of Glashow, Iliopoulos and Maiani's explanation of the suppression of strangeness-changing neutral currents was held in Shanghai.
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.
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.
The LHCb experiment has observed new beauty-baryon states, consistent with theoretical expectations for excited Ωb− baryons.
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.
