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...

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...
Read article 'Charm oscillations precisely measured by LHCb'
Direct searches for particles beyond the Standard Model (SM) have so far come up empty handed, but perhaps physicists can get luckier with indirect searches. Quantum mechanics allows neutral flavoured...
Read article 'Beauty quarks test lepton universality'
Recent meassurements of the decays of B mesons hint at slight deviations form lepton universality
Read article 'Rare hyperon-decay anomaly under the spotlight'
The LHCb collaboration has shed light on a long-standing anomaly in the very rare hyperon decay Σ+ → pµ+µ– first observed in 2005 by Fermilab’s HyperCP experiment. The HyperCP team found ...
