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.

References

Among these are the apparent unnaturalness of the electroweak scale, the particle nature of dark matter (DM), and the origin of the observed flavor hierarchies. These open problems suggest the existence of new physics beyond the SM (BSM) and have motivated extensive theoretical and experimental efforts to uncover it.
