«Rare B-Meson Decay Anomalies Hint at New Physics Beyond Standard Model, CMS and LHCb Repor» — τι περιλαμβάνει αυτή η σελίδα του δικτύου. At the International Conference on High Energy Physics (ICHEP), the CMS and LHCb collaborations presented new measurements of the ultra-rare decay of a beauty quark into a strange quark and a muon-antimuon pair (b→sμ⁺μ⁻). These decays are extremely suppressed in the Standard Model, making them sensitive probes for potential new particles or forces. The latest results from both experiments show deviations from theoretical predictions, with LHCb's updated branching fraction and angular analyses continuing to favor a lower-than-expected rate in certain kinematic regions.
CMS, using proton-proton collision data from the LHC, also reports a consistent pattern, though with larger uncertainties. The combined significance of the anomalies remains below the discovery threshold, but the agreement between independent detectors strengthens the case for a genuine effect.
