Briefings

The International Conference on High Energy Physics (ICHEP) featured presentations by the CMS and LHCb collaborations regarding the rare decay of a beauty quark into a strange quark, a muon, and an antimuon. This process, b→sμμ, serves as a stringent test of the Standard Model. The evidence indicates that while the Standard Model predicts this decay, the observed data suggests potential deviations that require further investigation. The study was conducted at the International Conference on High Energy Physics (ICHEP) in 2026, with the specific date of the conference not provided in the source. The evidence does not specify the exact energy levels or collision energies used in the experiments, nor does it provide the precise statistical significance of the observed deviations. The research remains pending for confirmation by independent experiments and further theoretical analysis.
