Dark matter, Higgs boson, gravity

Click For Summary

Discussion Overview

The discussion revolves around the relationships between dark matter, the Higgs boson, and gravity. Participants explore theoretical connections, particle interactions, and implications for our understanding of gravitational phenomena.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants question how dark matter particles interact with the Higgs boson and whether their mass is derived from the Higgs mechanism or other processes.
  • There is mention of baryonic matter's mass being primarily attributed to color confinement in quantum chromodynamics rather than the Higgs boson.
  • Several gravitational phenomena, such as galaxy rotation speeds and gravitational lensing, are noted as being inadequately explained by Newtonian gravity and general relativity, suggesting either unseen matter or gaps in our understanding of gravity.
  • Some participants advocate for dark matter theories, proposing that our knowledge of particle physics may be incomplete, with potential undiscovered particles and symmetries.
  • Alternative theories like modified Newtonian dynamics (MOND) are discussed, which propose adjustments to gravitational calculations under specific conditions.
  • Various models for dark matter are mentioned, including supersymmetric models and axion particles, with discussions on how these particles might acquire mass.

Areas of Agreement / Disagreement

Participants express multiple competing views on the interactions between dark matter, the Higgs boson, and gravity, with no consensus reached on the relationships or mechanisms involved.

Contextual Notes

There are unresolved questions regarding the assumptions behind dark matter interactions and the definitions of terms used in the discussion. The complexity of gravitational phenomena and the various models proposed highlight the ongoing exploration in this area.

How are related these 3 concepts?

Black matter, you mean dark matter, right?

What are your own investigations regarding this?

You have tagged the thread "A" which means you want replies on a phd/graduate level, are you aware of that? Or do you want us to reply in a "B" i.e. more like popular science level? Let me/us know and we get back you with a reply on an approriate level.

Cheers

You mean Black Lives Matter?

No politics on this forum.

Yes. I am Portuguese where the translation of “dark matter” is sometimes not well done.
thank you by the alert

I am a retired chemical engineer so “A” is not correct. How can I change it?

Your thread title has been fixed up and the thread prefix adjusted by the Mentors. :smile:

How do YOU think they are related? What do you understand each of them to be?

I think it is unknown how dark matter particles interact with the Higgs Boson, if their mass is due to the higgs boson or some other mechanism. Btw most of the mass of the baryonic matter is mostly due to a phenomenon named "Color Confinement" of the quantum chromodynamics and not due to the higgs boson.

Connection to gravity: several gravitational phemomena such as rotation speeds of galaxies, speeds of galaxies in galaxy clusters, gravitational lensing of single galaxies - are not explainable using calculations of such phenomena with Newtonian gravity and general relativity. The reason for this is either that there is more matter than what is visible (interact via electromagnetism) or that we simply do not understand gravity, or have missed something else in our calculations. Dark matter advocators means that it is more plausible that our understanding of particle physics is lacking - there are more particles and symmetries and such out there to be found.

Non-particle proposals for the anomalous gravitational observations mentioned includes MOND (modified Newtonian dynamics) in which there is also a small correction term to the gravitational force. This correction term is small for objects with low acceleration. But for objects that have high acceleration, such as stuff rotating far from the galaxy center (centripetal acceleration) this term grows rather large. Furthermore there are also people re-investigating general relativity performing new calculation on rotational curves.

As mentioned by @Delta2 it is not understood how dark matter particles attain mass, there are many models out there. Dark sectors, as was mentioned, for instance. There are also supersymmetric models where the "Neutrialino" particle can make up dark matter. Such particle would gain some of its mass from the regular Higgs-mechanism and some of its mass from the mechanism that breaks supersymmetry (since supersymmetry is not an exact symmetry of nature at low energies it has to be broken somehow). There are also models with axion particles.
