Read article 'Novel charmonium spectroscopy at LHCb'
The LHCb collaboration has published the result of precision mass and width measurements of the χc1 and χc2 charmonium states, performed for the first time by using the newly discovered decays χc1...
Read article 'LHCb digs deeper into lepton-flavour universality'
The LHCb collaboration has released yet another result in its campaign to test lepton-flavour universality. Following anomalies already detected in the rate that B mesons decay into muons compared to ...

Radius parameters versus average transverse kaon-pair momentum determined from K0S – K± correlations and identical-kaon correlations in central ALICE lead–lead collisions. The a0(980) ...
Read article 'The rarest B0 decay ever observed'
The LHCb collaboration has observed the rare baryonic decay B0 → pp, as first presented at the European Physical Society conference in Venice in early July. The branching fraction was measured a...

Read article 'LHCb discovers new baryon'
The LHCb collaboration has discovered a new weakly decaying particle: a baryon called the Ξ++cc, which contains two charm quarks and an up quark. The discovery of the new particle, which was observed...
Read article 'Belle II rolls in'
On 11 April, the Belle II detector at the KEK laboratory in Japan was successfully “rolled-in” to the collision point of the upgraded SuperKEKB accelerator, marking an important milestone for the ...
Read article 'LHCb finds new hints of Standard Model discrepancy'
At a seminar at CERN on 18 April, the LHCb collaboration presented new results in flavour physics that show an interesting departure from Standard Model (SM) predictions. The new measurement concerns ...
Read article 'Rare decay puts Standard Model on the spot'
The decay rate of the B0s meson to two muons is a flagship measurement in flavour physics. It is extremely rare and well predicted in the Standard Model (SM), with a branching fraction of (3.65±0.23)...
