Electroweak symmetry breaking without Higgs boson?

In summary, Xavier Calmet's paper discusses the concept of asymptotically safe weak interactions, particularly in relation to the Higgs field. It suggests that the Higgs field may not be necessary as a propagating particle and could simply serve as a dressing field. This interpretation could lead to the renormalizability of electroweak interactions at the non-perturbative level. The paper also mentions the restoration of tree-level unitarity in electroweak bosons scattering through the running of the weak scale. The concept of a dressing field may challenge current theories and could have implications for the LHC, hierarchy problem, fine-tuning, higgs quadratic radiative corrections, SUSY, strings, and future physics research and quantum

Asymptotically safe weak interactions
Xavier Calmet
(Submitted on 26 Dec 2010)
"We emphasize that the electroweak interactions without a Higgs boson are very similar to quantum general relativity. The Higgs field could just be a dressing field and might not exist as a propagating particle. In that interpretation, the electroweak interactions without a Higgs boson could be renormalizable at the non-perturbative level because of a non-trivial fixed point. Tree-level unitarity in electroweak bosons scattering is restored by the running of the weak scale."

What is a dressing field?

Could this paper be correct? If true, what would it mean for the LHC, hierarchy problem, fine-tuning, higgs quadratic radiative corrections, SUSY, strings, and future physics research and QG?

We really got rid of a couple of weird theories with the Higgs boson discovery.
 

FAQ: Electroweak symmetry breaking without Higgs boson?

1. What is electroweak symmetry breaking without Higgs boson?

Electroweak symmetry breaking without Higgs boson refers to a theoretical concept in particle physics where the mechanism responsible for breaking the symmetry between the electromagnetic and weak nuclear forces does not involve the Higgs boson. This alternative theory proposes that there may be other particles or interactions that can achieve the same effect without the need for the Higgs boson, which has not yet been observed experimentally.

2. Why is the Higgs boson considered the key to electroweak symmetry breaking?

The Higgs boson is considered the key to electroweak symmetry breaking because it is the particle predicted by the Standard Model of particle physics to be responsible for giving mass to other particles. Without the Higgs boson, the Standard Model cannot fully explain how particles acquire mass, and it is therefore a crucial component in understanding the fundamental forces and particles in the universe.

3. What evidence supports the existence of electroweak symmetry breaking without Higgs boson?

Currently, there is no experimental evidence that supports the existence of electroweak symmetry breaking without Higgs boson. However, some theoretical models, such as Technicolor and Supersymmetry, propose alternative mechanisms for electroweak symmetry breaking that do not involve the Higgs boson. These models have not yet been confirmed by experiments, but they are actively being studied by physicists.

4. How does electroweak symmetry breaking without Higgs boson impact our understanding of the universe?

If electroweak symmetry breaking without Higgs boson is proven to be true, it could significantly impact our understanding of the fundamental forces and particles in the universe. It would mean that there are other mechanisms at play, beyond the Higgs boson, that determine how particles acquire mass and interact with each other. This could lead to a deeper understanding of the fundamental nature of the universe and potentially open up new avenues for research and technological advancements.

5. What are the implications of not finding the Higgs boson for electroweak symmetry breaking?

If the Higgs boson is not found, it would mean that the current understanding of electroweak symmetry breaking is incomplete. This could lead to a re-evaluation of the Standard Model and a search for alternative theories. It could also mean that the Higgs boson has different properties than what is predicted by the Standard Model, which would require further research to understand its role in electroweak symmetry breaking.
