Electroweak scale naturalness problem

Establish a theoretically consistent mechanism that resolves the apparent unnaturalness of the electroweak scale within or beyond the Standard Model, identifying how the electroweak scale is stabilized without fine-tuning.

Background

The paper frames its motivation by noting foundational gaps in the Standard Model. One of these is the apparent unnaturalness of the electroweak scale, a longstanding issue suggesting fine-tuning in the Higgs sector absent new physics.

The authors’ proposed muon parton distribution function approach at a future muon collider is intended as a precision probe for light, weakly-coupled new physics, which could contribute to resolving this naturalness problem through indirect effects on kinematics across processes.
