Highlights of Flavour Violation in the Presence of a 4th Generation

We present a short overview of recent work on the topic of flavour violation in the presence of a sequential fourth generation (4G) of quarks and leptons. We discuss the implications of this simple extension of the Standard Model (SM3) for rare decays and CP violating observables. The observables of interest were chosen with the start of the LHC, the approval of SuperBelle and the upcoming NA62 experiment in mind. A special emphasis is placed on the importance of ε′/ε as a constraint for this model.
