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.
A major theme of the electroweak session was flavour physics, and the star of the show was LHCb’s observation of CP violation in charm decays.
The MEG II experiment is preparing to probe the muon’s flavour-violating decay to a positron and a photon with unprecedented sensitivity.
