Flavor physics in the quark sector and CP violation Denis Bernard, LLR

Understanding the weak decay of heavy quarks and CP violation in some of these decays has been instrumental in building the standard model of particle physics (SM). The full metrology of the Cabibbo-Kobayashi-Maskawa (CKM) mechanism performed since the begining of the century has shown that it describes completely these interactions, and the present (LHCb ..) and future (Belle II) efforts point to the detection of deviations that would be hints of physics beyond the SM. This lecture presents the CKM formalism, the dedicated experiments and some of the key measurements.

Neutrino physics Thomas Mueller, LLR

The experimental results obtained in the field of neutrino physics over the past thirty years have highlighted the phenomenon of flavor mixing in the leptonic sector and the massive character of neutrinos. This lecture will present the findings that have led to the discovery of neutrino oscillations. Our current knowledge in the light of recent measurements as well as remaining issues will be explicitly addressed. Theoretical aspects of the phenomenon of neutrino oscillation (flavor mixing, MSW effect...) will be presented; future experiments that could be set up in the coming years will be discussed. Flavor oscillations require a non-vanishing mass for the neutrinos. The Higgs mechanism of the minimal Standard Model which gives mass to elementary particles is not adequate explain why neutrinos have masses. This lecture will introduce several mechanisms, among the most natural and the most popular, to generate masses for these particles.
