Are extra-dimensions a possible explanation for electroweak symmetry breaking?

Click For Summary

Discussion Overview

The discussion revolves around the mechanisms of electroweak symmetry breaking, particularly in the context of the Higgs field and potential alternatives, including the role of extra dimensions. Participants explore various theoretical frameworks and models that could account for mass generation in particle physics.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant suggests that the inclusion of masses in the wave equation for W and Z bosons disrupts the underlying gauge symmetry, prompting the need for alternatives to the Higgs field.
  • Another participant recalls various mechanisms for mass generation and electroweak symmetry breaking, indicating that there are multiple approaches worth considering.
  • A third participant provides a reference to a paper that may address the question of electroweak symmetry breaking, suggesting that there are ongoing explorations in the field.
  • One participant mentions "topcolor" and composite/condensate mechanisms as potential alternatives to the Higgs field.
  • A question is raised about the feasibility of using extra dimensions as an explanation for electroweak symmetry breaking, indicating interest in this theoretical approach.

Areas of Agreement / Disagreement

Participants express a variety of viewpoints regarding the mechanisms of electroweak symmetry breaking, with no consensus reached on the validity or preference for any particular model. Multiple competing theories and ideas are presented, reflecting an ongoing debate.

Contextual Notes

Some discussions reference specific theoretical models and mechanisms without fully resolving their implications or interdependencies. The exploration of extra dimensions as a potential explanation remains speculative and is not universally accepted among participants.

Who May Find This Useful

Researchers and enthusiasts interested in particle physics, theoretical physics, and the ongoing debates surrounding electroweak symmetry breaking and alternative models may find this discussion relevant.

Higgs field is proposed because the brute force inclusion of masses into the wave equation of say the W and Z force-field quanta destroys the underlying Lie group gauge symmetry. What if the Large Hadron Collider can't find the Higgs Boson. What are the alternatives to Higgs field that mainstream physicists also entertain to be plausable?

Topcolor, or generically some composite/condensate mechanism
 
Can extra-dimensions be used to explain electroweak symmetry breaking?
