A novel technique by ATLAS uses top-quark pairs to test the ratio of the probabilities for tau leptons and muons to be produced in W-boson decays
LHCb will soon become the first LHC experiment able to run simultaneously with two separate interaction regions.
The collaboration scoured four months of electron-positron collisions at SuperKEKB for evidence of invisibly decaying Z′ bosons.
Updated measurements by LHCb of the angular distributions of a rare neutral B meson decay add fresh intrigue to the flavour puzzle.
The LHC’s physics programme has transformed our understanding of elementary particles, writes Michelangelo Mangano.
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.
Explaining the bizarre pattern of fermion types and masses has led theorists to suggest that the “flavour scale” could be at a much lower energy than previously thought.
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.
The 29th International Symposium on Lepton–Photon Interactions at High Energies provided a snapshot of the entire field.
