https://en.wikipedia.org/wiki/Naturalness_(physics)In physics, naturalness is the property that the dimensionless ratios between free parameters or physical constants appearing in a physical theory should take values "of order 1" and that free parameters are not fine-tuned. That is, a natural theory would have parameter ratios with values like 2.34

naturalness in nLab
https://ncatlab.org/nlab/show/naturalness- In (particle-)physics the term “naturalness” refers to the vague idea that a model of physics is expected to work without requiring unlikely-looking ad-hoc coincidences or “fine-tuning” of its parameters, and that instead all such “conspiracies” among parameter values are to have some systematic cause, such as some symmetryof the model. An archetypical example, which at tim…
What is naturalness ? | Physics Forums
https://www.physicsforums.com/threads/what-is-naturalness.57963824/02/2012 · Naturalness is a concept specific to effective field theory (EFT). An EFT is a description of the physics at energy scales below some cutoff [itex]\Lambda [/itex]. A simple illustration of an EFT is the following. Let's suppose that at high energies, we have a massless particle [itex]\phi [/itex] and a particle [itex]X [/itex] with mass [itex]M ...
