No evidence of “new physics” was found so far by LHC experiments, and this situation has led some voices in the physics community to call for the abandonment of the “naturalness” criterion, while other scientists have felt the need to break a lance in its defense by claiming that, at least in some sense, it has already led to successes and therefore should not be dismissed too quickly, but rather only reflected or reshaped to fit new needs. In our paper we will argue that present pro-or-contra… 

Naturalness and the Forward-Looking Justification of Scientific Principles

It has been suggested that particle physics has reached the "dawn of the post-naturalness era." I provide an explanation of the current shift in particle physicists’ attitude towards naturalness. I

A Natural Introduction to Fine-Tuning

A well-known topic within the philosophy of physics is the problem of fine-tuning: the fact that the universal constants seem to take non-arbitrary values in order for live to thrive in our Universe.

Dogmas of Effective Field Theory: Scheme Dependence, Fundamental Parameters, and the Many Faces of the Higgs Naturalness Principle

The earliest formulation of the Higgs naturalness argument has been criticized on the grounds that it relies on a particular cutoff-based regularization scheme. One response to this criticism has

Multiverse Theories

If the laws of nature are fine-tuned for life, can we infer other universes with different laws? How could we even test such a theory without empirical access to those distant places? Can we believe

Shadow Extra Dimensions&Fuzzy Branes with an Exorcized Spectrum

Particle physics models with extra dimensions of space (EDS’s) and branes allow to shed new light on naturalness of the electroweak and flavor sectors, with a rich TeV scale phenomenology. Usually,

Nuclear clocks for testing fundamental physics

The low-energy, long-lived isomer in 229Th, first studied in the 1970s as an exotic feature in nuclear physics, continues to inspire a multidisciplinary community of physicists. It has stimulated

Naturalness in nuclear effective field theories

Nuclear effective field theories (EFTs) have been developed over the last quarter-century with considerable impact on the description of light and even medium-mass nuclei. At the core of any EFT is a

Supersymmetry and R-symmetries in Wess-Zumino models: properties and model dataset construction

A pedagogical review on the basics of supersymmetry in (3+1)-dimensions, Wess-Zumino models and their supergravity extensions, the Nelson-Seiberg theorem and its extensions and an estimation of the accuracy of the field counting method based on these theorems are given.

Between Logos and Mythos Narratives of “Naturalness” in Today’s Particle Physics Community

At the core of today’s particle physics stands the Standard Model, a theory whose predictions have so far not been contradicted by any experimental result. Despite this success in the last decades

Two Notions of Naturalness

My aim in this paper is twofold: (i) to distinguish two notions of naturalness employed in beyond the standard model (BSM) physics and (ii) to argue that recognizing this distinction has

Screams for explanation: finetuning and naturalness in the foundations of physics

It is explained why the necessity to define a probability distribution renders arguments from naturalness internally contradictory, and why it is conceptually questionable to single out assumptions about dimensionless parameters from among a host of other assumptions.

Naturalness and the Status of Supersymmetry

For decades, the unnaturalness of the weak scale has been the dominant problem motivating new particle physics, and weak-scale supersymmetry has been the dominant proposed solution. This paradigm is

Naturalness, chiral symmetry, and spontaneous chiral symmetry breaking

A properly called “naturalness” is imposed on gauge theories. It is an order-of-magnitude restriction that must hold at all energy scales μ. To construct models with complete naturalness for
