CERN's LHCb Hints at New Physics in B-Meson Decays (4-Sigma Tension)
Researchers at CERN's LHCb observed ~650 billion B-meson decays and found a four-sigma discrepancy with Standard Model predictions in rare penguin-like decays, a potential hint of new physics. If confirmed, explanations could involve a Z' boson or leptoquarks; further analysis of data since 2018 and upgrades planned for the 2030s are expected to clarify whether this is genuine new physics or a statistical fluctuation.
