Abstract
Over the past three decades, the standard model (SM) of elementary particle physics has been established by many experimental verifications as the basic theory describing fundamental particles and their interactions at energy scales from \(\mathcal {O}(1)\) \(\mathrm {eV}\) to \(\mathcal {O}(1)\) \(\mathrm {TeV}\). However, serious theoretical open questions, and some puzzling experimental results lead to the common prejudice that the SM is an effective theory valid at the energies probed so far, which should be completed and complemented by a more general framework at higher energies.
