Read article 'ATLAS clocks rare decay of B mesons into muon pairs'
The decays of the B0s and B0 into muon pairs represent an important test of the Standard Model. Such decays take place through a flavour-changing neutral current process, which occurs only through loo...
Read article 'LHCb updates Bs oscillation measurement'
The LHCb experiment has recently made the most precise measurement yet of the asymmetry in oscillations between the matter and antimatter versions of Bs mesons. The measurement exploits the full LHCb ...

Read article 'World’s most precise measurements and search for the X(5568) tetraquark candidate'
At the Rencontres de Moriond EW conference held at La Thuile (Italy) from 12 to 19 March, the LHCb collaboration presented new important results. CKM γ-angle measurements. The parameters that descri...
Read article 'LHCb awards physics prizes for its Kaggle competition'
Machine learning, also known in physics circles as multivariate analysis, is used more and more in high-energy physics, most visibly in data analysis but also in other applications such as trigger and...
Read article 'BESIII makes first direct measurement of the Λc at threshold'
The charmed baryon, Λc, was first observed at Fermilab in 1976. Now, 40 years later, the Beijing Spectrometer (BESIII) experiment at the Beijing Electron–Positron Collider II (BEPCII) has measure...

Scientists from the DZero collaboration at the US Department of Energy’s Fermilab have discovered a new particle – the latest member to be added to the exotic species of particles known as tetraqu...
Read article 'LHCb brings charm physics to the frontier of experimental knowledge'
Owing to the large cross-section for charm production at the LHC, LHCb collected the world’s largest sample of charmed hadrons, allowing for stringent tests of the Cabibbo–Kobayashi–...
Read article 'Is the Standard Model about to crater?'
There are now quite a few discrepancies, or “tensions”, between laboratory experiments and the predictions of the Standard Model (SM) of particle physics. All of them are of the 2...
