A bstractThe relaxion mechanism is a novel solution to the hierarchy problem. In this first statistical analysis of the relaxion mechanism, we quantify the relative plausibility of a QCD and a non-QCD relaxion model versus the Standard Model with Bayesian statistics, which includes an automatic penalty for fine-tuning. We find that in light of the hierarchy between the weak and Planck scales, relaxion models are favoured by colossal Bayes-factors. Constraints upon e.g., the vacuum energy during… Expand

Relaxion: A Landscape Without Anthropics
The relaxion mechanism provides a potentially elegant solution to the hierarchy problem without resorting to anthropic or other fine-tuning arguments. This mechanism introduces an axion-like field,Expand
Dynamics of relaxed inflation
A bstractThe cosmological relaxation of the electroweak scale has been proposed as a mechanism to address the hierarchy problem of the Standard Model. A field, the relaxion, rolls down its potentialExpand

Expectations for inflationary observables: simple or natural?
We describe the general inflationary dynamics that can arise with a single, canonically coupled field where the inflaton potential is a 4-th order polynomial. This scenario yields a wide range ofExpand
Gravitational tests of electroweak relaxation
Abstract We consider a scenario in which the electroweak scale is stabilized via the relaxion mechanism during inflation, focussing on the case in which the back-reaction potential is generated byExpand
Bayesian naturalness, simplicity, and testability applied to the $B-L$ MSSM GUT using GPU Monte Carlo
The lack of decisive experimental results to settle fundamental questions in physics has led to increasing reliance upon intuitive criteria such as naturalness, simplicity, and testability. We argueExpand
Naturalness made easy: two-loop naturalness bounds on minimal SM extensions
A bstractThe main result of this paper is a collection of conservative naturalness bounds on minimal extensions of the Standard Model by (vector-like) fermionic or scalar gauge multiplets. Within, weExpand
