On the Physics Case of a Super Flavour Factory

We summarize the physics case of a high-luminosity e+e− flavour factory collecting an integrated luminosity of 50 − 75 ab. Many New Physics sensitive measurements involving B and D mesons and τ leptons, unique to a Super Flavour Factory, can be performed with excellent sensitivity to new particles with masses up to ∼ 100 (or even ∼ 1000) TeV. Flavourand CP -violating couplings of new particles that may be discovered at the LHC can be measured in most scenarios, even in unfavourable cases assuming minimal flavour violation. Together with the LHC, a Super Flavour Factory, following either the SuperKEKB or the SuperB proposal, could be soon starting the project of reconstructing the New Physics Lagrangian.
