The purpose of these lectures is to provide the reader with an idea of how we can probe New Physics with quark flavour observables using effective theory techniques. After giving a concise review of the quark flavour structure of the Standard Model, we introduce the effective Hamiltonian for quark weak decays. We then consider the effective Hamiltonian for ΔF=2 transitions in the Standard Model and beyond. We discuss how meson-antimeson mixing and CP violation can be described in terms of the ΔF=1 and ΔF=2 effective Hamiltonians. Finally we present the Unitarity Triangle Analysis and discuss how very stringent constraints on New Physics can be obtained from ΔF=2 processes.
