In physics research, results are frequently represented in complex diagrams, and colour is an essential tool to help the reader extract key information.  Making sure our colour schemes are friendly to people with colour-vision deficiency (CVD in…

Peter Higgs was one of the pioneers who brought the electroweak theory and the Standard Model of particle physics into being in the 1960s. He posited a new field and particle that would provide a mechanism for how elementary particles gain mass. The…

Following its mission to address fundamental questions about Nature, the Large Hadron Collider (LHC) has operated at different center-of-mass energies, colliding protons and/or heavy ions. In heavy ion collisions, the nucleons (protons and neutrons…

A fundamental parameter of the Standard Model, the electroweak mixing angle plays a key role in the “Higgs mechanism”, when the W and Z gauge bosons get their masses through electroweak symmetry breaking. CMS has now reported a new measurement of…

Cosmological observations tell us that Dark Matter makes up roughly 80% of all the matter in the Universe. However, no Dark Matter particle has ever been observed. To verify whether it can be produced in the laboratory, the CMS Collaboration at the…

    The J/ψ meson, a remarkable particle simultaneously discovered by two independent experiments in 1974, has a unique place in the world of experimental particle physics. By revealing the existence of an extra “flavour” of quarks, it played an…

If you have ever had Neapolitan gelato, you know how important it is to combine three different flavours, each in just the right size. And the Standard Model (SM) of particle physics is not less tasty than that! In the SM, leptons are some of the…

The discovery of the Higgs boson (H), particularly with its decay into two electroweak gauge bosons WW and ZZ, marked a milestone in particle physics. This groundbreaking discovery not only answered long-standing questions but also inspired new…
