Naturally Unnatural

Abstract

This year’s EPS-HEP was somewhat subdued. We will have to wait another two years before the LHC restarts and we can again follow every talk expecting the unexpected. This is just a good time to look back and ask what we learned so far from the LHC. We have seen that the Higgs sector is probably fine-tuned at least by some small factor. However, many physicists dislike fine-tuning. They feel that the laws of physics should be naturally derived from a simple model that leaves no room for such ambiguity. The multiverse provides a natural explanation for the unnatural parameters of physics but many people hate the very idea of the multiverse.
