The upcoming announcement from the LHC on December 20 is expected to address potential violations of lepton universality, a significant anomaly in high-energy physics that contrasts with Standard Model predictions. Recent analyses of B+→K+ℓ+ℓ− and B0→K∗0ℓ+ℓ− decays indicate that previous anomalies may have diminished with improved data quality, showing results consistent with Standard Model expectations. The analysis utilizes data from LHCb's Run 1 and 2, achieving higher signal purity and sensitivity than earlier tests. There is speculation that the discrepancies observed in related experiments, such as the muon g-2, could stem from theoretical prediction issues rather than new physics. Overall, the findings suggest a narrowing possibility for new physics at energy scales accessible by current and future colliders.
