New SMOG on the horizon

LHCb will soon become the first LHC experiment able to run simultaneously with two separate interaction regions.

First physics for Belle II

The collaboration scoured four months of electron-positron collisions at SuperKEKB for evidence of invisibly decaying Z′ bosons.

Anomalies persist in flavour-changing B decays

Updated measurements by LHCb of the angular distributions of a rare neutral B meson decay add fresh intrigue to the flavour puzzle.

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.
