| Résumé≠ | Charge-Parity (CP) violation measurement is the experimental study of asymmetries between particle and antiparticle processes, a fundamental probe of physics beyond the Standard Model. By comparing decay rates and asymmetries in kaons, B mesons, and neutrinos, physicists constrain new sources of CP violation and address the cosmological matter-antimatter imbalance. | Neutrino oscillation analysis is the study of flavor mixing in the neutrino sector, where neutrinos born as one flavor (electron, muon, or tau) spontaneously convert into other flavors as they propagate. Measuring oscillation parameters provides crucial evidence for physics beyond the Standard Model and tests our understanding of the neutrino mass hierarchy. |
