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...

Large Hadron Collider Physics (LHCP2017) conference took place at Shanghai Jiao Tong University (SJTU) in China
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 ...

A look back at the Fermilab experiment that unearthed the b quark.
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)...
Read article 'Exotic hadrons bend the rules'
Half a century after the quark model was devised, a number of hadrons appear to challenge its axioms. But are they truly exotic?
Read article 'LHCb sees first hints of CP violation in baryons'
The LHCb experiment has uncovered tantalising evidence that baryons made of matter behave differently to those made of antimatter, violating fundamental charge-parity (CP) symmetry. Although CP-violat...
Read article 'ALICE studies beauty in the quark–gluon plasma'
In high-energy nucleus–nucleus collisions, heavy-flavour quarks (charm and beauty) are produced on a very short time scale in initial hard-scattering processes and thus they experience the entire ev...
