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.
The LHCb collaboration recently reported the results of searches for two complementary charged-lepton-flavour violating decays.
LHCb’s amplitude analyses contain the largest CP asymmetry in a single component of an amplitude analysis, found in the ππ ↔ KK re-scattering amplitude.
Recent experimental results hint that some electroweak processes are not lepton-flavour independent.
