LHC at 10: the physics legacy

The LHC’s physics programme has transformed our understanding of elementary particles, writes Michelangelo Mangano.

Opening gambit for LHCb in the V_cb puzzle

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.

Who ordered all of that?

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.

Flavour heavyweights converge on Ljubljana

Highlights of Beauty 2019 included lepton-universality anomalies, CP violation, pentaquarks, ultra-rare decays and reports on Belle II and the LHCb upgrade.

Debut for baryons in flavour puzzle

LHCb has introduced Λ_b⁰ decays as a new probe of the flavour anomalies.

Lepton–photon interactions in Toronto

The 29th International Symposium on Lepton–Photon Interactions at High Energies provided a snapshot of the entire field.

Chasing charged-lepton-flavour violation

The LHCb collaboration recently reported the results of searches for two complementary charged-lepton-flavour violating decays.

Three-body B⁺ decays violate CP

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.
