Abstract：

Theories with (classical or quantum) scale-invariance provide a dynamical origin of all mass scales and present a number of interesting aspects: they are an appealing framework to address the hierarchy problem and lead to naturally flat potentials and dark matter candidates. In this talk, I will briefly introduce the scale-invariance in the approach of beyond the standard model. I will concentrate on the general arguments of scale-invariance, by considering two explicit example: the hidden scalar QCD and the Electroweak Bosonic Seesaw Mechanism.
