There exist renormalisation schemes that explicitly preserve the scaleinvariance of a theory at the quantum level. Imposing a scale invariantrenormalisation breaks renormalisability and induces new non-trivial operatorsin the theory. In this work, we study the effects of such scale invariantrenormalisation procedures. On the one hand, an explicitly quantum scaleinvariant theory can emerge from the scale invariant renormalisation of a scaleinvariant Lagrangian. On the other hand, we show how a quantum scale invarianttheory can equally emerge from a Lagrangian visibly breaking scale invariancerenormalised with scale dependent renormalisation (such as the traditionalMS-bar scheme). In this last case, scale invariance is hidden in the theory, inthe sense that it only appears explicitly after renormalisation.
