Read article 'Doubly strange baryon observed in Japan'
Experimental evidence was first reported in the 1970s, but there has been a lingering theoretical controversy about the interpretation of both states.
Read article 'LHCb discovers two new baryons'
By studying new hadronic resonances and their excited states, light can be shed on the mechanisms governing the dynamics of the strong force.
Read article 'LHCb tests consistency of unitarity triangle'
The unitarity triangle exists in the complex plane and its area is a measure of the amount of CP violation in the Standard Model.
Read article 'Heavy-flavour highlights from Beauty 2018'
In recent years, several puzzling anomalies have emerged from LHCb and b-factory data, and discussion of these set the scene for a very inspiring atmosphere at the conference.
Read article 'CMS resolves inner structure of bottomonium'
Bottomonium mesons play a special role in our understanding of hadron formation because the large quark mass allows important simplifications in the relevant theoretical calculations.
Read article 'Charmed baryons strike back'
Last year, the LHCb collaboration announced the first observation of the Ξcc++ baryon, a doubly charmed particle (CERN Courier July/August 2017 p8). It was identified via the decay Ξcc++ → Λc...
Read article 'SuperKEKB steps out at the intensity frontier'
On 26 April the SuperKEKB accelerator at the KEK laboratory in Japan collided its first beams of electrons and positrons, marking the start of an ambitious data-taking campaign that will allow ultrapr...
Read article 'Central exclusive production at LHCb'
Four years ago, LHCb measured the central exclusive production (CEP) of J/ψ and ψ(2S) mesons at a centre-of-mass energy of 7 TeV (CERN Courier March 2014 p7). In CEP, two incoming protons emerge i...

The annual conference is an opportunity to review the progress taking place over the breadth of particle physics.
Read article 'First hints of ultra-rare kaon decay'
The NA62 collaboration at CERN has found a candidate event for the ultra-rare decay K+ → π+ ν ν, demonstrating the experiment’s potential to test heavily-suppressed corners of the Stand...
