Abstract: There are two important clues to go beyond the SM of particle physics, i.e. the naturalness problem and the stability of the vacuum. I will first explain why they suggest that the Higgs potential should be completely flat at a very high energy scale, e.g. M_{Pl}. Based on these observations, I will then introduce a model, a classically conformal B-L extension of the SM, in which the EWSB is radiatively generated. I will also give a necessary condition for the radiative symmetry breaking starting from a completely flat potential at M_{Pl}.
