Concepts of naturalness are present in many disciplines of science. In particle physics the concept of naturalness, as formulated by e.g. P.A.M. Dirac and G. ‘t Hooft, has guided the quest for constructing the next fundamental model of Nature beyond our current Standard Model of Particle Physics. This quest is currently also guided by results from experiments such as the Large Hadron Collider at CERN.
I will review some of the known shortcomings of the current Standard Model of Particle Physics and how they relate to our concept of naturalness on the smallest length scales we have so far probed in the lab. As part of this I will assess the naturalness of nature and how we might arrive at a new model beyond the current Standard Model of Particle Physics.
