Abstract: In perturbative QFT, the standard approach to renormalisation often involves very balanced “fine-tunings” between large quantum corrections and corresponding “counterterms”. For many, such a fine-tuning feels “unnatural” and requires an explanation. This problem goes under the name “hierarchy problem” and has motivated tons of new physics models. However, we come up with a new approach to renormalisation which does not require such tuning. The existence of this method shows that the hierarchy problem is nothing but an unphysical, formalism-dependent artefact
