LHCb probes lepton universality with taus

The collaboration's latest test of lepton-flavour universality with beauty baryons brings a further tool to understand the flavour anomalies.

Beauty enhances precision of CKM angle γ

Comparisons between direct and indirect measurements of γ provide a potent test for new physics.

Beyond bumps

The inaugural CERN Flavour Anomalies Workshop brought together more than 500 experimentalists and theorists to discuss longstanding tensions in B-physics measurements.

LHCb studies the intrinsic charm of the proton

The possibility that the proton wave function may contain a |uudcc̄> component in addition to the g → cc̄ splitting arising from perturbative gluon radiation has been debated for deca...

LHCb tests lepton universality in new channels

New measurements of the rates of rare B-meson decays to electrons and muons open a further avenue through which to explore the flavour anomalies.

B_s decays remain anomalous

The LHCb experiment recently presented new results on the b → sμμ decay of a B_s meson to a φ meson and a dimuon pair.

Building the future of LHCb

LHCb's brand-new “SciFi” tracker and upgraded ring-imaging Cherenkov detectors are vital for the higher LHC luminosities ahead.

COMPASS points to triangle singularity

The collaboration last week reported the first direct evidence for the long-sought interplay between hadron decays, downplaying the chances that the a₁(1420) is a new exotic hadron.

New tetraquark a whisker away from stability

The new state, announced today at EPS-HEP, had been held up since the 1980s as a prime candidate to be the first exotic hadronic state to be stable against strong decays.
