The most accurate measurement of rare meson decay confirms modern physics

All physical theories are simplified representations of reality, and as a consequence, have a specified range of applicability. Many scientists working on the LHCb experiment at CERN had hoped that the exceptional accuracy in the measurement of the rare decay of the Bs0 meson would at last delineate the limits of the Standard Model, the current theory of the structure of matter, and reveal phenomena unknown to modern physics. But the spectacular result of the latest analysis has only served to extend the range of applicability of the Standard Model.
