Studying beautiful flavour transitions

Rare Processes in Particle Physics

Studying rare phenomena is crucial in particle physics as it provides stringent tests of the Standard Model. Researchers working at CERN continue to measure fundamental interactions with unprecedented precision to understand the building blocks of the universe.

Measurements from CMS and LHCb

At the International Conference on High Energy Physics (ICHEP), the CMS and LHCb Collaborations presented their latest results on the b→sμ+μ– process. In this transition, a beauty quark decays into a strange quark, a muon, and an oppositely charged antimuon. The detailed measurements aim to determine the exact rates of these flavour transitions.

Implications for Physics Beyond the Standard Model

Detailed analyses of flavour transitions allow physicists to check for subtle discrepancies between theoretical predictions and experimental results. Uncovering deviations in these rare decays could offer key evidence for the existence of unknown particles or forces in nature.
