In these three lectures, I overview the theoretical framework of the flavour
physics and CP violation. The first lecture is the introduction to the flavour
physics. Namely, I give theoretical basics of the weak interaction. I follow
also some historical aspect, discovery of the CP violation, phenomenological
studies of charged and neutral currents and the success of the GIM mechanism.
In the second lecture, I describe the flavour physics and CP violating
phenomena in the Standard Model (SM). I also give the latest experimental
observation of the CP Violation at the B factories and the LHC and discuss its
interpretation. In the third lecture, I discuss the on-going search of the
signals beyond SM in the flavour physics and also the future prospects.Comment: 26 pages, contribution to the 1st Asia-Europe-Pacific School of
