LHCb observes four new tetraquarks

The collaboration has used Run 2 data to add new exotic states to the tally of tetraquarks previously discovered in B⁺→J/ψφK⁺ decays in 2016.

LHCb sheds light on V_ub puzzle

LHCb has recently published a new result on |V_ub| using the first ever measurement of the B_s⁰→K^–μ⁺ν_μ decay.

Heavy-flavour highlights from Beauty 2020

Flavour studies have a bright future, concluded conference delegates, who discussed impressive recent results in CP violation and the status of Belle II and upgrades to the LHC experiments.

J/ψ polarisation differs in lead collisions

Work now turns to connecting such observations with the known suppression and regeneration mechanisms in heavy-ion collisions.

CMS reaffirms exotic nature of the X(3872)

The tetraquark candidate could be a bound state of a charm-up diquark and its anti-diquark.

ICHEP’s online success

Advances in Higgs, flavour and neutrino physics were among the highlights of ICHEP 2020, writes Mark Thomson.

Double digits for ultra-rare kaon decay

CERN’s NA62 collaboration has presented 3.5σ evidence for K⁺→π⁺νν̄ – a “golden decay” with exceptional sensitivity to physics beyond the Standard Model
