摘要：
37 years after the discovery of CP violation in pi(+)pi(-) decays of neutral K-mesons, the experiments BABAR and BELLE have found a second system which violates CP symmetry. J/psiK(S)(0) decays of neutral B-mesons show very large symmetry breaking. The effect has now, with the most recent data, a significance of ten standard deviations. The presentation describes the B-meson factories, the experiments, and their analyses. The results are in agreement with the Standard Model explanation of CP violation, i.e. with different couplings of the Higgs boson to quarks and antiquarks.
