Why do we observe a weak force? The hierarchy problem in the multiverse

TL;DR

This paper explores why the weak force is weak by examining the multiverse, suggesting that weakless universes could be more common and that the hierarchy problem requires a dynamical solution rather than an anthropic one.

Contribution

It links the hierarchy problem to multiverse theory and shows that weakless universes are more prevalent, challenging anthropic explanations for the weak force's strength.

Findings

Weakless universes can support life with proper parameter adjustments.

Weakless universes are more common than universe like ours.

The hierarchy problem favors a dynamical solution.

Abstract

Unless the scale of electroweak symmetry breaking is stabilized dynamically, most of the universes in a multiverse theory will lack an observable weak nuclear interaction. Such "weakless universes" could support intelligent life based on organic chemistry, as long as other parameters are properly adjusted. By taking into account the seemingly-unrelated flavor dynamics that address the hierarchy of quark masses and mixings, we show that such weakless (but hospitable) universes can be far more common than universes like ours. The gauge hierarchy problem therefore calls for a dynamical (rather than anthropic) solution.
