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.

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.

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.

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...

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...

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...

Standard Model gets annual check up at Moriond

The annual conference is an opportunity to review the progress taking place over the breadth of particle physics.

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...

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...
